structural and optical properties of InxGa1-xN/GaN epilayers grown on a miscut sapphire substrate
I. A. Ajia, S. M. C. Miranda, N. Franco +4
We report on structural and optical properties of InGaN/GaN thin films, with a 0.46o misalignment between the surface and the (0001) plane, which were grown by metal-organic chemic…
Defect-impurity complex induced long-range ferromagnetism in GaN nanowires
Assa Aravindh S, Iman S Roqan
Present work investigates the structural, electronic and magnetic properties of wurtzite (0001) GaN nanowires (NWs) doped with Gd and point defects by employing the GGA+U approxima…
Defect induced d0 ferromagnetism in a ZnO grain boundary
S. Assa Aravindh, Udo Schwingenschloegl, Iman S. Roqan
Several experimental studies have referred to the grain boundary (GB) defect as the origin of the ferromagnetism in ZnO. However, the mechanism of this hypothesis has never been co…
