The hetero-epitaxial growth of Fe3O4 thin films on ZnO is studied in the context of opto-spintronic applications, paying a thorough attention to the interface optimization. The samples are grown by pulsed laser deposition using either Fe2O3 or Fe3O4 targets. Firstly, we establish the Fe3O4 growth windows at various oxygen partial pressures and...

Deuterium diffusion is investigated in nitrogen-doped homoepitaxial ZnO layers. The samples were grown under slightly Zn-rich growth conditions by plasma-assisted molecular beam epitaxy on m-plane ZnO substrates and have a nitrogen content [N] varied up to 5 × 1018 at cm-3 as measured by secondary ion mass spectrometry (SIMS). All were exposed...

ZnO nanowires (NWs) are very attractive for a wide range of nanotechnological applications owing to their tunable electron concentration via structural and surface defect engineering. A 2D electrical profiling of these defects is necessary to understand their restructuring dynamics during engineering processes. Our work proposes the exploration...
