DETAILS, FICTION AND BAGA4SE7 CRYSTAL

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