RUMORED BUZZ ON BAGA4SE7 CRYSTAL

′�?, with a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical theory computations display that the residual absorption in the BGSe crystal originate
