文摘
We propose and experimentally validate a theoretical closed-form modeling procedure for ZnO-based heterojunction ultraviolet (UV) photodetectors. To do so, we first employ a deposition and growth method based on chemical bath deposition for a typical ZnO/CuO n–p heterojunction structure. The UV detection performance of this type of detector has been examined and confirmed previously. The fabricated device was then tested, and its performance analyzed. We model the performance of the detector by extension of previously proposed analytical models and study the performance of the device. The results show good agreement between the measurements and theoretical modeling.
