Abstract: | In this paper, the ZnO nanorods/n+-Si heterojunction was fabricated by growing vertical and compact ZnO nanorods on heavily doped n type silicon wafer using a low-temperature aqueous solution method. The influences of different annealing time under 630℃ on the I-V characteristic of the ZnO nanorods/n+-Si heterojunction were studied, and the experimental results revealed that the rectification behaviours of the I-V curves were greatly enhanced by increasing the annealing time, and the reason was studied in this work. |
