EXAMINE THIS REPORT ON BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−one phonon corresponds on the crystal IR absorption edge, in lieu of the residual absorption peak. Density purposeful idea computations present that the residual absorption of the BGSe crystal originates f
