HELPING THE OTHERS REALIZE THE ADVANTAGES OF BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−one phonon corresponds to your crystal IR absorption edge, rather than the residual absorption peak. Density practical principle computations present that the residual absorption of your BGSe crystal or
