(a) CL peak position (Eemi) of present impurity transition (solid stars) observed from Fig. 1 and those of (VIII complex)1− related transitions (solid squars) obtained from undoped AlxGa1 − xN alloys as a function of AlN mole fraction x in Ref. [16]; (b) EA versus AlN mole fraction for (VIII-complex)1−, Ev, Ec, and ED.
