Transport in fused InP nanowire device in dark and under illumination: Coulomb staircase scenario
نویسندگان
چکیده
Electron transport is discussed for an ensemble of fused conical indium phosphide nanowires bridging two hydrogenated n-silicon electrodes. The current-voltage (Id-Vd) characteristics exhibit a Coulomb staircase in dark with a period of ~ 1 V but it disappears under light illumination in some devices, while Id-Vd is featureless smooth monotonic curve in other devices. It is shown that transport is dominated by a single NW pair in dark, while many NW pairs will contribute to transport under illumination.
