NOT KNOWN FACTS ABOUT BAGA4SE7 CRYSTAL

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