« Transphorm showcasing new automotive-grade AEC-Q101-qualified GaN FET for PHEVs and EVs | Main | DOE: 58% of BEV sales in US in 2016 were large cars and standard SUVs; PHEVS mainly compact and midsize » ZAF Energy Systems Inc. (ZAF), developer of a rechargeable Nickel Zinc (NiZn) battery, announced that it is in field testing with a leading US manufacturer of commercial trucks, buses, and defense vehicles. The testing began in Q1 2017 with ZAF passing the manufacturer’s rigid battery performance testing requirements and is currently in field tests that will end in the third quarter of 2017. The field tests will put the NiZn batteries through real world operational situations such as high-temperature use, regenerative braking, and extended use in a Class 8 sleeper truck. During the testing, four ZAF NiZn batteries will take on the same workload as the eight lead acid batteries that are typically used in eighteen-wheel commercial long haul trucks. The reduction in the number of batteries translates to an estimated weight savings of 480 pounds. ZAF’s system also fully supports 10-hour cycles for mandatory rest periods, regenerative braking, removes the need for engine driven accessories, and eliminates the possibility of alternator failures. The NiZn battery also reduces life cycle maintenance costs by 50% due to idle reduction. ZAF is now heavily engaged with several large multi-national trucking companies, further proving the significant value opportunity we create for our partners and customers through value-added battery solutions. We believe that our battery technology can remove certain barriers from outdated battery chemistries that are impairing the trucking industry to enable the electrification of next generation trucks and drive improved fuel efficiency. ZAF’s nickel-zinc battery weighs significantly less yet yields twice the storage capacity and three times the power of the conventional lead-acid batteries that are used for commercial trucking, start-stop delivery vehicles, and deep-cycle industrial and recreational applications. On a life cost per kilowatt-hour basis, it is half the cost of lead acid.

The sensing of infrared radiation enables optical communications, night vision, health monitoring, spectroscopy and object inspection6. For this reason, many efforts have sought to integrate infrared detection onto silicon to combine infrared sensing with state-of-the-art electronics7. The ideal infrared photodetector must combine a fast response, high responsivity and low power consumption with facile fabrication8. Early efforts in this direction based on epitaxial semiconductors such as III-V and germanium4, 5, 9 added complexity in the fabrication process due to epitaxial crystal growth requirements and the need to mitigate silicon contamination and doping8. Recently, black silicon was reported—an infrared-sensitive material obtained using laser treatment of the silicon surface10, 11, 12. However, this technology suffers from low responsivity (10−2−10−1 A W−1) at infrared wavelengths10. Colloidal quantum dots (CQDs) have enabled photodetectors13 that benefit from infrared sensitivity, high light absorption14, wavelength tunability15, low cost and room-temperature solution processing. However, CQDs have yet to be integrated successfully with silicon. In a heterojunction photodiode16 or traditional photo-field-effect transistor (photo-FET), modest transport in the quantum dot solid limits the performance of the device. A new architecture is required that is not curtailed by the photoconductive effect—a mechanism that produces photodetectors that are either responsive but slow, or fast but unresponsive17. Here we present a Si:CQD photovoltage field-effect transistor (PVFET). It exploits a photovoltage that arises at the Si:CQD interface to control junction electrostatics. As a result, it modulates the conductivity of the silicon channel in proportion to incident light at wavelengths below that of the bandgap of silicon. The Si:CQD PVFET shows high responsivity in the infrared (1,300 nm and 1,500 nm) in excess of 104 A W−1, a response that is faster than 10 μs, and dark current densities of 10−1−101 A cm−2 for a gate–source voltage of V = 0–3 V. We explain and demonstrate the physical principles that govern the operation of the PVFET using simulations and analytical models, and show the potential of the device when fabricated using the state-of-the-art silicon techniques currently employed in the electronics industry. In Fig. 1a we show the structure of the Si:CQD PVFET. A lightly p−-type silicon channel is epitaxially grown on an n+ silicon substrate that acts as a gate. The channel is contacted with ohmic aluminium source and drain (see Supplementary Information section S1). A thin n-doped CQD film is deposited on top of the silicon channel, creating an infrared-photosensitive gate. The source and drain were covered with a thick layer of insulating silicon nitride to prevent electrical contact between the photogate and the aluminium. The means of deposition of the CQD layer is crucial to the operation of the device. The rectifying Si:CQD junction relies on the passivation of surface traps and providing energetic alignment between the two semiconductors. In the absence of judiciously engineered heterointerface passivation, the two semiconductors fail to produce an efficient rectifying heterojunction16. Figure 1e shows the transverse energy band diagram of the PVFET: the thin (1.6 μm) silicon p-doped layer is sandwiched between two n-type rectifying junctions and is therefore depleted at equilibrium (in the dark). Simulations (Fig. 1c, d) illustrate the working principles of the device. Upon optical illumination using 1,300-nm incident radiation (Fig. 1c), photocarriers are generated exclusively within the CQD solid. This produces a photovoltage at the interface via the photovoltaic effect—the same effect that produces an open-circuit voltage in solar cells. In the PVFET, this effective bias shrinks the depletion region and thereby increases the extent of the (undepleted) channel in the silicon. Figure 1d shows the density of holes (majority carriers) in the silicon channel in the dark and under 1,300-nm illumination. We analyse the operation of the PVFET to further explain the physical mechanisms that govern its behaviour and compare its performance with that of other photodetector architectures (Fig. 2). The gain as a function of the dark current for the PVFET, photodiodes, photoconductors and photo-FETs have been analysed (Fig. 2a). Photoconductors and photo-FETs (that is, previously developed CQD-based phototransistors) are treated together because the gain mechanism that governs these devices is the same: trap-assisted photoconductivity18, 19. Diodes do not produce gain20; photoconductors and photo-FETs have a linear relationship between photoconductive gain G and dark current I : G = τ /τ , where τ is the trap lifetime and τ is the transit time within the channel, which is related to I through the electrical mobility (see Supplementary Information). The gain can be increased by decreasing the transit time, that is, by using a high-mobility channel (for example, graphene18); however, doing so increases the dark current. In the PVFET, gain is adjusted by tuning the doping of the channel; the effect of the gate allows high gain at low dark current. The gain produced by the PVFET is hν/q × V g /P (see Supplementary Information section S3) where h is the Planck constant, ν is the optical frequency, q is the elemental charge, V is the photovoltage, P is the incident optical power and g is the transconductance of the PVFET, which is defined as g = dI /dV , where I is the source–drain current. We compared this analytical model to fully self-consistent numerical simulations (TCAD) and found good agreement, especially at high current (Fig. 2a); the analytical model does not accurately capture the subthreshold regime. Gain based on photovoltage and transconductance is distinct from photoconductive gain. It enables simultaneously high signal amplification and rapid response20 (Fig. 2c). Whereas photoconductors and photo-FETs are limited in speed by τ , and rely on traps to produce gain13, the bandwidth of the PVFET is instead determined by the total capacitance, resulting in an operating frequency of f = g /C , where C is the total capacitance. As can be seen in Fig. 2c, whereas gain is generated in photoconductors and photo-FETs at the expense of speed (CQD photo-FETs are typically limited to response times in the range 0.001–1 s owing to the required high values of τ )19, 21, in the PVFET, high gain (high g ) leads to a rapid response time. This gain mechanism allows for a large G × BW product, as shown in Fig. 2b. Here, we achieve experimentally a G × BW product of 104 × 105 s−1 and we show (Fig. 2c), using the model of gain and bandwidth (see Supplementary Information section S9 for details of the model), that this value can in principle be further increased towards 105 × 108 s−1. The performance of the PVFET depends strongly on the quality of the Si:CQD rectifying junction (Supplementary Information sections S4, S11 and S12). The photovoltage that arises at the heterojunction interface is crucially determined—as in a solar cell, which also relies on the photovoltaic effect—by the rectification ratio of the junction; therefore, it is important to minimize the reverse saturation current of the junction (see Supplementary Information section S3). The PVFET converts the photovoltage signal to a photocurrent through the transconductance, which, in a junction transistor, also depends on the quality of the heterojunction. A highly rectifying, trap-free heterointerface must be engineered to produce efficient PVFETs. This approach distinguishes the device from previously reported photo-FETs based on CQDs. In these devices, gain comes from trap-assisted photoconduction; that is, the traps provided by the CQD film are responsible for the long lifetime of the photocarriers recirculating in a high-mobility channel (for example, graphene or MoS ). This produces a gain of τ /τ (the ratio between the lifetime of the CQD trap and the transit time of the charge in the channel). These devices do not require a rectifying photogate and their gain arises not from a transistor effect, but from a photoconductive one. We fabricated Si:CQD PVFETs and characterized their performance. First, we investigated the spectral response of the detector. We report the gain (Fig. 3a; defined as the external quantum efficiency, which is given by the ratio between the numbers of photocarriers and incident photons) as a function of the wavelength. The device produces a gain of about 6 × 104 at the exciton. The excitonic peak (at either 1,300 nm or 1,500 nm) is characteristic of the CQD solid, and its energy is determined by the effect of quantum confinement, with greater spatial confinement increasing the effective bandgap of the CQD solid22. In Fig. 3a we compare the detector to a PVFET that lacks a CQD photogate (a silicon-only device), and to black silicon photodetectors12. The sensitivity of the silicon-only device vanishes beyond the bandgap of silicon at 1,100 nm. The gain of the PVFET remains high, owing to the high absorption of the CQD photogate at these longer wavelengths. The comparison with black silicon photodetectors reveals a responsivity at infrared wavelengths that is five orders of magnitude higher in the case of the PVFET. We further characterized the PVFET, measuring its responsivity at 1,300 nm as a function of incident power. The gain of 104 at low intensity begins to roll off near about 2 × 10−5 W cm−2. Figure 3b shows this result, along with that predicted using the analytical model, in which the responsivity is calculated as g V /P . The device exhibits gain compression at high illumination, requiring offline nonlinearity correction, but also enabling increased dynamic range21. The responsivity of the PVFET as a function of V and source–drain voltage V (Fig. 3c) saturates for V > 2 V, which corresponds to the saturation voltage of the transistor (for voltages higher than the saturation voltage, the transconductance g remains constant; see Supplementary Information section S2), and vanishes for increasing V . Positive V closes the channel (full depletion), which markedly decreases g (ref. 20): , where G is a constant of the device, V is the built-in voltage of the junction and V is the pinch-off voltage of the PVFET (more details on the static behaviour of the PVFET are provided in Supplementary Information section S2). We proceeded to investigate the temporal response of the detector. Figure 4a, b shows the response of the PVFET to a square wave. It shows fast (10 μs) fall and rise edges of the signal. This component of temporal response is compatible with sensing and imaging, addressing a wide range of consumer applications. The PVFET has a much faster response time than do traditional CQD-based photoconductors (about 100 ms). A slower tail, attributable to defect states in the highly doped silicon substrates and the CQD bulk and interface, is also seen in the experimentally fabricated PVFETs. Removing these electronic states could increase the response time of PVFETs towards 1 GHz (the limit arising from g /C , as shown in Fig. 2), making them competitive with photodiodes and enabling applications such as time-of-flight sensing and machine vision1. In Fig. 4c, the signals acquired from the Si:CQD PVFET and the silicon-only device are compared. The two waveforms representing the response to a 100-kHz excitation are similar, with the PVFET presenting slightly sharper edges. (additional data are provided in Supplementary Information section S6). Notably, the addition of the CQD layer does not affect the transient response of the silicon device: it preserves its original speed, consistent with the fact that the PVFET gain mechanism does not rely on a memory effect from traps. We measured the noise performance of the detector as a function of frequency, and found flicker noise at low frequencies (corner frequency at approximately 100 kHz) and a plateau at high frequencies that approaches the shot-noise limit (Supplementary Information section S5). The CQD photogate does not introduce additional noise to the silicon structure. We measured the noise current and obtained a detectivity of D* = 1.8 × 1012 jones (1 jones = 1 cm Hz1/2 W−1). We also compared the device to previous CQD detectors. If we define a figure of merit that accounts for the responsivity (where BW is the bandwidth), the speed of response and the dark current density J , then the Si:CQD PVFET outperforms previous CQD-based detectors by at least one order of magnitude (Supplementary Information section S7). Traditional CQD-based photo-FETs and photoconductors are outperformed, owing to their lack of bandwidth; CQD diodes, which have a lower I , lack reponsitivity and so have a lower F compared to the PVFET. The Si:CQD PVFET has high gain (>104), even in the infrared (wavelengths of >1,500 nm), high speed (100 kHz) and contained dark current (10−1−101 A cm−2). This performance can be improved further by using advanced silicon processing. The advances reported here were possible only by devising an architecture that combines the benefits of silicon electronics with the emerging potential of CQDs. This architecture leverages a detection mechanism based on the photovoltaic effect combined with transconductive gain.

The team, led by Won-Ju Cho of Kwangwoon University in Seoul, based their device on the 'dual-gate field-effect transistor' (DG FET). When molecules bind on a field-effect transistor, a change happens in the surface's electric charge. This makes FETs good candidates for detecting biological and chemical elements. Dual-gate FETs are particularly good candidates because they amplify this signal several times. But they can still be improved. The team used a method called 'nanoimprint lithography' to fabricate silicon nanowires onto the surface of a DG FET and compared its sensitivity and stability with conventional DG FETs. Field-effect transistors using silicon nanowires have already been drawing attention as promising biosensors because of their high sensitivity and selectivity, but they are difficult to manufacture. The size and position of silicon nanowires fabricated using a bottom-up approach, such as chemical vapor deposition, cannot always be perfectly controlled. Top-down approaches, such as using an electron or ion beam to draw nanorods onto a surface, allow better control of size and shape, yet they are expensive and limited by low throughput. Cho and his colleagues fabricated their silicon nanowires using nanoimprint lithography. In this method, a thin layer of silicon was placed on top of a substrate. This layer was then pressed using a nanoimprinter, which imprints nano-sized wire-shaped lines into the surface. The areas between separate lines were then removed using a method called dry etching, which involves bombarding the material with chlorine ions. The resultant silicon nanowires were then added to a DG FET. The team found that their device was more stable and sensitive than conventional DG FETs. "We expect that the silicon-nanowire DG FET sensor proposed here could be developed into a promising label-free sensor for various biological events, such as enzyme–substrate reactions, antigen–antibody bindings and nucleic acid hybridizations [a method used to detect gene sequences]," conclude the researchers in their study published in the journal Science and Technology of Advanced Materials.

The charge transport and microstructural properties of five different molecular weight (MW) batches of the naphthalenediimide-thiophene copolymer P(NDI2OD-T2) are investigated. In particular, the field-effect transistor (FET) performance and thin-film microstructure of samples with MW varying from M = 10 to 41 kDa are studied. Unlike conventional semiconducting polymers such as poly(3-hexylthiophene) where FET mobility dramatically drops with decreasing molecular weight, the FET mobility of P(NDI2OD-T2)-based transistors processed from 1,2-dichlorobenzene is found to increase with decreasing MW. Using a combination of grazing-incidence wide-angle X-ray scattering, near-edge X-ray absorption fine-structure spectroscopy, atomic force microscopy, and resonant soft X-ray scattering, the increase in FET mobility with decreasing MW is attributed to the pronounced increase in the orientational correlation length (OCL) with decreasing MW. In particular, the OCL is observed to systematically increase from <100 nm for the highest MW samples to ≈1 µm for the lowest MW samples. The improvement in OCL and hence mobility for low MW samples is attributed to the lack of aggregation of low MW chains in solution promoting backbone ordering, with the pre-aggregation of chains in 1,2-dichlorobenzene found to suppress longer-range liquid crystalline order.
