چکیده انگلیسی
We have performed first-principles density functional theory calculation in order to investigate the feasibility of “p-n codoping method” in improving magnetic property of In2O3 based diluted magnetic semiconductors. We find that the ferromagnetic state is favored in Mn-doped In2O3, and Sn doping can increase magnetic moment in Mn-doped In2O3. These findings are in line with our earlier experimental observation. Along with previous works, we now have enough evidences to support that p-n codoping is a valid method to improve magnetism of oxides based diluted magnetic semiconductors.
