High performance broadband photodetector using fabricated nanowires of bismuth selenide.
Recently, very exciting optoelectronic properties of Topological insulators (TIs) such as strong light absorption, photocurrent sensitivity to the polarization of light, layer thickness and size dependent band gap tuning have been demonstrated experimentally. Strong interaction of light with TIs has been shown theoretically along with a proposal for a TIs based broad spectral photodetector havi...
متن کاملBroadband photodetector based on carbon nanotube thin film/single layer graphene Schottky junction
In this study, we present a broadband nano-photodetector based on single-layer graphene (SLG)-carbon nanotube thin film (CNTF) Schottky junction. It was found that the as-fabricated device exhibited obvious sensitivity to a wide range of illumination, with peak sensitivity at 600 and 920 nm. In addition, the SLG-CNTF device had a fast response speed (τr = 68 μs, τf = 78 μs) and good reproducibi...
متن کاملZnO nanowires array grown on Ga-doped ZnO single crystal for dye-sensitized solar cells
High quality ZnO nanowires arrays were homoepitaxial grown on Ga-doped ZnO single crystal (GZOSC), which have the advantages of high conductivity, high carrier mobility and high thermal stability. When it was employed as a photoanode in the DSSCs, the cell exhibited a 1.44% power-conversion efficiency under the illumination of one sun (AM 1.5G). The performance is superior to our ZnO nanowires/...
متن کاملReduction of persistent photoconductivity in ZnO thin film transistor-based UV photodetector
We report a ZnO-based thin film transistor UV photodetector with a back gate configuration. The thin-film transistor (TFT) aspect ratio W/L is 150 lm/5 lm and has a current on-off ratio of 10. The detector shows UV-visible rejection ratio of 10 and cut-off wavelength of 376 nm. The device has low dark current of 5 10 14 A. The persistent photoconductivity is suppressed through oxygen plasma tre...
متن کاملA Comparative Photocatalytic Activity of ZnO/SiO2 and V2O5-ZnO/SiO2 by Investigating the Degradation of Rhodamine B
ZnO/SiO2 was prepared using sol-gel method, and vanadium particles were loaded on this nano-photocatalyst by wet incipient method. They characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) analysis andFouriertransform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure and vanadium dope...
