Photodiode comprising a transparent fluorine-doped tin oxide (FTO) layer, an active layer of a wide-bandgap semiconductor and an ionizable metal electrode, in which the active layer has been oxidized for 1-10 minutes at a temperature between 600 and 625. The photodiode thus manufactured has the highest photovoltaic field ever observed in a photovoltaic device. This enormous (MV/cm) photovoltaic field makes unprecedented above-bandgap voltages viable for very thin (less than 1 m) thin-film devices.

Nano- and micromotors are nano- and microscale devices, respectively, designed to perform selected mechanical movements in response to specific stimuli. They are built from a few nano- and microscale components, each of which can be biologically or chemically functionalized, and operate using some type of energy input. Over the past decade, researchers have shown increased interest in nano- and micromotors. The development and application of these devices are among the most pressing challenges in current nanoscience and nanotechnology. The videos contained in the Supporting Information clearly demonstrate that nanomotors are no longer the subject of science fiction. Also included in the Supporting Information are tables that summarize the main advances in composition and operation for each class of nano- and micromotor.

This critical review represents a concise revision of the different experimental approaches so far followed for the structuration of molecular nanomagnets on surfaces, since the first reports on the field more than ten years ago. Afterwards, a presentation of the different experimental approaches followed for their integration in sensors is described. Such work involves mainly two families of sensors and devices, microSQUIDs sensors and three-terminal devices for single-molecule detection. Finally the last section is devoted to a detailed revision of the different experimental techniques that can be used for the magnetic characterization of these systems on surfaces, ranging from magnetic circular dichroism to magnetic force microscopy. The use of these techniques to characterize other nanostructured magnetic materials, such as nanoparticles, is also revised. The aim is to give a broad overview of the last advances achieved with these techniques and their potential and evolution over the next years.

Flexoelectricity allows a dielectric material to polarize in response to a mechanical bending moment and, conversely, to bend in response to an electric field. Compared with piezoelectricity, flexoelectricity is a weak effect of little practical significance in bulk materials. However, the roles can be reversed at the nanoscale. Here, we demonstrate that flexoelectricity is a viable route to lead-free microelectromechanical and nanoelectromechanical systems. Specifically, we have fabricated a silicon-compatible thin-film cantilever actuator with a single flexoelectrically active layer of strontium titanate with a figure of merit (curvature divided by electric field) of 3.33 MV-1, comparable to that of state-of-the-art piezoelectric bimorph cantilevers. © 2015 Nature Publishing Group

Physical Review B - Condensed Matter and Materials Physics | Year: 2012

First-principles calculations of substitutional defects and vacancies are performed for zigzag-edged hybrid C/BN nanosheets and nanotubes which recently have been proposed to exhibit half-metallic properties. The formation energies show that defects form preferentially at the interfaces between graphene and BN domains rather than in the middle of these domains, and that substitutional defects dominate over vacancies. Chemical control can be used to favor localization of defects at C-B interfaces (nitrogen-rich environment) or C-N interfaces (nitrogen-poor environment). Although large defect concentrations have been considered here (106 cm -1), half-metallic properties can subsist when defects are localized at the C-B interface and for negatively charged defects localized at the C-N interface; hence the promising magnetic properties theoretically predicted for these zigzag-edged nanointerfaces might not be destroyed by point defects if these are conveniently engineered during synthesis. © 2012 American Physical Society.

Half-semimetallicity has been predicted to occur in zigzag-shaped graphene ribbons embedded in BN sheets. Using first-principles density-functional calculations a physical explanation is given, showing that the magnetism of the edge states in graphene strips and polarity effects in BN strips team up to give a spin asymmetric screening that induces an electronic reconstruction and half-semimetallicity at the interface, with a gap of at least a few hundreds of millielectron volts for one spin orientation and a tiny gap of tens of millielectron volts for the other. The dependence with ribbon widths is discussed, revealing that a range of ribbon widths is required to obtain the half-semimetallic state. These results prove that unconventional physical effects similar to those observed at insulating oxide interfaces, can also exist in lower dimensions, opening alternative routes for tuning electronic properties at nanointerfaces. © 2010 The American Physical Society.
