Capacitance-Voltage (C-V) Properties of ZnO:Al/p-Si Heterojunctions

Abstract

ZnO:Al/p-Si heterojunctions were fabricated by sol-gel dip coating technique onto p-type Si wafer substrates. Capacitance-Voltage (C-V) characteristics of ZnO:Al/p-Si heterojunctions were determined after the ZnO:Al thin film coated Si wafers were annealed at 700 and 800°C, respectively. C-V results indicate an abrupt interface.
