EXAMINE THIS REPORT ON BAGA4SE7 CRYSTAL

′�?, using a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds for the crystal IR absorption edge, rather then the residual absorption peak. Density purposeful idea computations display that the residual absorption of your BGSe crystal originat
