Substrate-Dependent Differences in the Crystal Structures and Optical Properties of ZnSe Nanowires

Substrate-Dependent Differences in the Crystal Structures and Optical Properties of ZnSe Nanowires

The optical and structural properties of ZnSe nanowires directly grown on three different substrates, SiO2, ITO, and graphene, were investigated. ZnSe nanowires grown on graphene and SiO2 were found to have cubic structures, while ZnSe nanowires grown on ITO had a mixed cubic and hexagonal structure...
