nanowires-based UV photodetectors have been extensively studied. However
the large dark current limits its further applications. In this paper
a single In

nanowire ultraviolet phototransistor is performed. Through the modulation of the back gate voltage
the dark current is almost completely depleted. At the same time
the threshold voltage shows a shift under illumination
leading to little dependence between gate voltage and photocurrent. Finally
