Fig. 3From: Simulation Analysis on Photoelectric Conversion Characteristics of Silicon Nanowire Array PhotoelectrodesElectrostatic potential distributions. X axis is the NW radial direction, and X = 0 corresponds to the NW center; Y axis is the NW longitudinal direction, and Y = 0 corresponds to the interface between the NWs and substrate. a–e The N d is 2.19 × 1014, 2.34 × 1015, 3.07 × 1016, 4.0 × 1017, and 1.31 × 1018 cm−3, respectivelyBack to article page
