High performance single In2Se3 nanowire photodetector

摘要

The single In2Se3 nanowire photodetectors were fabricated and the performance characteristics of the NW devices were systematically investigated. The single In2Se3 NW photodetectors show high and stable photoresponse at wide light wavelength (254–800 nm) and temperature range (7–300 K). The spectra response curve indicates the absorption coefficient of the In2Se3 NWs at certain wavelength dominates the performance of the devices. The good linearity of the photocurrents with the incident irradiation over a wide wavelength range has been obtained, indicating the In2Se3 nanowire photodetector works under a typical light dependent resistor mode.
