Distinctive mapping of strain and quantum size effects using depth-resolved photoluminescence in ZnO nanoneedles
In order to locate the spatially resolved influence of the strain, carrier localization, and quantum size effect (QSE) in tapered ZnO nanoneedles (NNs), the photoluminescence (PL) was measured as a function of the incident laser angle θ from 0∘ (normal to a surface) to 85∘. With increasing θ, the ex...
