Defect-impurity complex induced long-range ferromagnetism in GaN nanowires
Present work investigates the structural, electronic and magnetic properties of Gd doped wurtzite GaN nanowires (NWs) oriented along the [0001] direction in presence of intrinsic defects by employing the GGA + U approximation. We find that Ga vacancy (V _Ga ) exhibits lower formation energy compare...
