“…Therefore, we can expect the formation of excitons bound to 1As4Ga clusters embedded in wide band gap AlN:(Ga, As). SA of similar tetrahedral clusters was described for a number of III-V and II-VI semiconductors double doped with isoelectronic impurities [6][7][8][9]. This study is devoted to SA of isoelectronic impurity clusters in triple doped semiconductors that are not considered yet.…”
