摘要

The present work reports the fabrication and detailed electrical properties of heterojunction diodes based on p-type Si and the reduced graphene oxide-based TiO2 (TiO2:RGO) composite. The enhanced dark conductivity was observed for TiO2:RGO composite films. The improved electrical conductivity is considered to mainly come from the mobility enhancement. The TiO2/p-type Si diode shows a poor rectifying behavior and low photoresponse. This is because of the dominance of electron traps in TiO2. However, the TiO2:RGO/p-type Si diode shows a good rectifying behavior and high photoresponse, which is attributed to high-mobility electron transport combined with the reduced number of electron traps.
