RUMORED BUZZ ON BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density useful principle computations exhibit which the residual absorption with the BGSe crystal ori
