NOT KNOWN FACTS ABOUT BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical concept computations present that the residual absorption of the BGSe crystal originates
