RUMORED BUZZ ON BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density useful theory computations exhibit which the residual absorption of the BGSe crystal originates
