Experimental evidences for reducing Mg activation energy in high Al-content AlGaN alloy by Mg(Ga) δ doping in (AlN)(m)/(GaN)(n) superlattice
P-type doping in high Al-content AlGaN alloys is a main challenge for realizing AlGaN-based deep ultraviolet optoelectronics devices. According to the first-principles calculations, Mg activation energy may be reduced so that a high hole concentration can be obtained by introducing nanoscale (AlN)(5...
