Abstract:
Flexible electronics and optoelectronics devices attract further attention in recent years. In this paper, we present the fabrication and photodetection properties of a flexible metal-semiconductor-metal UV photodetector based on a thin ZnO film with Pd Schottky electrodes. The active ZnO layer was created using a hydrothermal method on ITO/PET flexible substrates. Palladium employed as back-to-back Schottky contacts. Metal masks are designed and used to deposit palladium via thermal evaporation. To demonstrate the impact of ZnO on flexible substrates, the structural, optical, and electrical c

AbstractIn this study, we present a simple ultraviolet (UV) light photodiode by transferring a layer of graphene film on single-crystal ZnO substrate. The as-fabricated heterojunction exhibited typical rectifying behavior, with a Schottky barrier height of 0.623 eV. Further optoelectronic characterization revealed that the graphene-ZnO Schottky junction photodiode displayed obvious sensitivity to 365-nm light illumination with good reproducibility. The responsivity and photoconductive gain were estimated to be 3×104 A/W and 105, respectively, which were much higher than other ZnO nanostructure
