Thin Solid Films | Year: 2016

In this paper, Ga-doped ZnO (GZO) thin films are deposited on glass substrates by radio frequency magnetron sputtering for low loss plasmonic applications. The effects of Ga2O3 content in the target and substrate temperature on the electrical, structural and optical properties of GZO films are investigated. Film with the highest carrier concentration of 7.0 × 1020 cm- 3 was obtained at a Ga2O3 content of 5 wt% in the target under room temperature deposition. With increasing deposition temperature, the lowest electrical resistivity of 3.8 × 10- 4 Ω cm was acquired at a deposition temperature of 200 °C. The values of plasmonic resonances wavelength could be changed from 1.35 to 2.39 μm by adjusting the carrier concentration. Material absorption losses in these GZO films are 10 times lower than that of conventional Ag films at telecommunication wavelengths. These results make GZO a promising low-loss plasmonic material operating at telecommunication wavelengths. © 2015 Elsevier B.V. All rights reserved. Source

The flexible transparent conductive films (FTCFs) of silver nanowire-polyethylene terephthalate (AgNW-PET) were prepared by a facile method including vacuum filtration and mold transferring. The effect of silver nanowire weight density on the optical and electrical properties of films, as well as the electrical percolation was investigated. The obtained typical AgNW-PET film exhibited high figure of merit of 31.3 × 10-3 Ω-1 with low sheet resistance of 4.95 Ω sq-1 and high transparency at 550 nm of 83.0% (excluding PET substrate). The resulting FTCFs based on PET substrate with high transmittance and low sheet resistance have a great potential in the application of high-performance flexible electronics and photovoltaic devices. © 2015.

Abstract Transparent and conductive silver nanowires (AgNWs)-filled methylcellulose (MC) composite films were fabricated by blending silver nanowires (AgNW) with a methylcellulose solution. AgNW concentration showed significant influence on the optical, electrical and mechanical properties of composite films. The percolation threshold of AgNWs-filled methylcellulose composite films in this study was approximately 0.29 vol%. A three-dimensional (3D) network-like composite film with micron-scale thickness demonstrated the electrical percolation of the two-dimensional (2D) network. Methylcellulose blended with silver nanowires showed enhanced mechanical properties such as tensile strength and Young's modulus compared with pure methylcellulose matrix. © 2015 Elsevier B.V.

Morphology-controllable Cu2SnS3 thin films on Mo-glass were prepared via a facile in situ one-step solvothermal process and used in dye-sensitized solar cells as counter electrodes. The effects of different solvents on the morphology of films were investigated. DSC based on the porous net-like Cu2SnS3 thin film as counter electrodes showed a power conversion efficiency of 2.30%, which was improved to 3.35% after annealing. © The Chinese Society for Metals and Springer-Verlag 2015.
