RUMORED BUZZ ON BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical theory computations show that the residual absorption from the BGSe crystal or
