NOT KNOWN DETAILS ABOUT BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density purposeful concept computations display which the residual absorption in the BGSe crystal orig
