The work presents a systematic study of energetic N-2(+) ion interaction with the clean Al2O3 surface at room temperature. Energetic N-2(+) ions with energies ranging from 0.1 to 5 keV were bombarded onto the c-plane Al2O3 ...

The difference in the evolution of dislocation mediated low-dimensional GaN nanostructures on differently pre-nitrided c-plane sapphire surfaces is demonstrated. We show that GaN growth on c-plane sapphire, after forming ...

The performance of perovskite solar cells is strongly influenced by the composition and microstructure of the perovskite. A recent approach to improve the power conversion efficiencies utilized mixed-halide perovskites, ...
