Abstract

A highly sensitive ultraviolet detector (UV) sensor composed of ZnO nanosheets/Cu2O heterostructure was fabricated. It composed of two dimensional ZnO nanosheets and Cu2O film. The photoresponse results showed that the fabricated UV detector were sensitive to UV light illumination with good stability and reproducibility. The high UV response performance can be attributed to heterojunction formation and large surface area provided by ZnO sheets-like structures. The results indicated the suitability of the simple and low-cost ZnO nanosheets/Cu2O heterojunction device for optoelectronic applications..
