Dark and IR photocurrent versus voltage plots, and log-log plots of the current-voltage. (a) Dark and IR photocurrent versus voltage plots of the InN NRs/n-Si heterojunction diode. The inset shows the schematic diagram of diode. (b) Log-log plots of the current-voltage under forward bias of InN NRs/n-Si heterojunction measured at room temperature. The I-V plot is divided into three different regions.
