Abstract

Electron transport is discussed for an ensemble of fused conical indium phosphide nanowires bridging two hydrogenated n⁺-silicon electrodes. The current-voltage (I_d-V_d) characteristics exhibit a Coulomb staircase in dark with a period of ~ 1 V but it disappears under light illumination in some devices, while I_d-V_d 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.sentati
