THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, that has a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, rather then the residual absorption peak. Density purposeful concept computations demonstrate that the residual absorption of the BGSe
