′�?, having a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, rather then the residual absorption peak. Density purposeful idea computations show which the residual absorption of your BGSe crystal origin
