We investigate the potential of epitaxial (001)p-NiO/(0001)n-ZnO heterostructures grown on (0001)sapphire substrates by pulsed laser deposition technique for ultraviolet (UV) photodetector application. Our study reveals that in the self-powered mode, these devices can serve as effective photodetecto...
