Abstract

Vertical aligned p-Si nanowires were fabricated by electroless wet chemical etching of Si wafer. p-Si nanowires/ZnO thin film heterojunction diode was fabricated by depositing ZnO thin film on vertically aligned p-Si nanowire arrays. Optical studies revealed that the Si nanowire surface has porous silicon like structure. The junction properties were evaluated by measuring I-V and C-V characteristics. I-V characteristics exhibited well defined rectifying behavior with a turn-on voltage of 2.26 V and ideality factor of 4.5.
