ABSTRACT
We have investigated the photoelectrical properties of p-type selenium nanowire field effect transistors. The hole concentrations are estimated to be 4.1×1017 and 2.5×1018 cm-3 for the device under dark and illumination, respectively. The photoelectrical on/off ratio can be tunable from 4 to 160 as the gate voltage decreases from 20 to -20 V.
