Development of Al Doped ZnO Nanowalls Based Flexible, Ultralow Voltage UV Photodetector

摘要

throughout the measurements. The external quantum efficiency was 1827.8% at 5 V applied bias. The proposed ultralow voltage UV PD demands very low power and, therefore, could potentially lengthen the battery discharge time. Additionally, a prominent UV sensitive piezoelectric response, having dark voltage to photo voltage ratio of 24.5, has been demonstrated that has made the device a potential candidate for fast response time, self-powered PD.
