Performance Optimization of ZnO/TiO2/NPB Heterojunction for Visible-Blind UV Photodetectors via SCAPS-1D Simulation
This work presents a detailed numerical optimization of an ITO/ZnO/TiO₂/NPB heterostructure for visible-blind ultraviolet (UV) photodetection. The device incorporates a thin TiO₂ interfacial layer between the inorganic ZnO electron transport layer and the organic NPB hole transport/absorbing layer. We systematically in...
