Abstract

Quasi-monocrystal ZnO film grown using the hydrothermal growth method is used for the fabrication of Cu/ZnO heterojunction (HJ) ultraviolet photodetectors (UV-PDs). The HJ was formed via the sputtering deposition of p-type Cu onto hydrothermally grown ZnO film (HTG-ZnO-film). The effect of annealing temperature in the nitrogen ambient on the photoluminescence spectra of the synthesized ZnO film was studied. The optoelectronic properties of Cu/ZnO film with various Cu thicknesses (250-750 nm) under UV light (365 nm; intensity: 3 mW/cm²) were determined. The UV sensitivity of the HTG-ZnO-film-based UV-PDs and the sputtered ZnO-film-based UV-PDs were 55.6-fold (SHTG) and 8.8-fold (Ssputter), respectively. The significant gain in sensitivity (SHTG/Ssputter = 630%) of the proposed ZnO-film-based device compared to that for the device based on sputtered film can be attributed to the improved photoelectric properties of quasi-monocrystal ZnO film.
