In this work, we fabricated a novel BeZnO based dual‐color UV photodetector through a one‐step electron beam evaporation of asymmetric Ti/Au pair. A dual‐phase BeZnO alloy film with dual bandgap of ∼3.5 eV (∼355 nm) and ∼4.6 eV(∼270 nm) was artfully utilized as active layer to realize dual‐color response. This photodetector shows a noticeable photovoltaic characteristic and can be utilized as an excellent...
A high‐performance UV photodetector (PD) based on a p‐Se/n‐ZnO hybrid structure with large area (more than 1×1 cm) is presented in this study. The device is theoretically equivalent to a parallel‐connection circuit for its special structure and shows multifunction at different voltage bias, which means the output signal can be tailored by an applied voltage. The Se/ZnO PD shows binary response (positive...
