Formation of Mn-Sin complexes in GaN: A first principles investigation
چکیده انگلیسی
Using first principles calculations, we study the relative spatial distribution of Mn and Si impurities in the host matrix of GaN. It stems from our investigation that the co-doping of (Ga,Mn)N with Si will result in the formation of Mn-Si complexes with a large absolute pairing energy of 2.27 eV. The formation of such complexes is energetically feasible already at the growth surface. According to our results, larger complexes involving two Si ions are also possible in bulk but exhibit a much smaller absolute pairing energy. Finally, the co-doping of (Ga,Mn)N with Si results in the reduction of the charge state of Mn from 3+ to 2+ regardless of the relative position of Si and Mn in the gallium sublattice.
