Abstract: The structure of MBE-grown ZnO layers was investigated along with RF sputtered layers at around 600 • C followed by a higher temperature anneal. The ZnO layers were either deposited directly on sapphire or on top of a GaN template. After the MBE growth on (0001)GaN, the analysed layers contain a large density of defects and the interface is not completely coherent on some 2-3 monolayers. In the case of RF sputtering, the samples comprised an Mn-doped part towards the surface on top of about a 150 nm pure ZnO …
