DETAILS, FICTION AND BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful idea computations demonstrate the residual absorption from the BGSe crystal orig
