摘要

The degraded performance of annealed ZnO-based photodetector can be recovered by embedding Ag ₂ O nanoparticles resulted from the transformation of as-deposited Ag layer. After thermal treatment, the electrons were attracted at the interface between ZnO and Ag ₂ O. The excess Ag ⁺ ions form the cluster to incorporate into the interstitial sites of ZnO lattice to create a larger amount of lattice defects for the leakage path. The photo-current of ZnO film with Ag ₂ O nanoparticles is less than annealed ZnO film because the photo-induced electrons would flow into Ag ₂ O side. ZnO photodetector with the appropriate Ag ₂ O nanoparticles possesses the best rejection ratio.
