Abstract
The Bi2Se3/ZnO heterostructure is a new combination of high- and low-band-gap nanomaterials that can be implemented for optoelectronic devices. The influence of the Bi2Se3 substrate on crystallization of ZnO nanolayers and charge separation at the Bi2Se3/ZnO interface reflects these important parameters, which affect optical and electronic properties of the heterostructure. Despite a few studies on Bi2Se3/ZnO heterostructures, the mechanisms of enhanced optical properties and correlation between optical and structural properties in such heterostructures are not studied in detail. In the present paper, we report on structure and optical properties of ZnO nanolaye...
