NOT KNOWN FACTS ABOUT BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, rather then the residual absorption peak. Density practical idea computations exhibit which the residual absorption with the BGSe crystal origina
