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 on the 295 cm−one phonon corresponds towards the crystal IR absorption edge, rather than the residual absorption peak. Density practical principle computations exhibit that the residual absorption on the BGSe crystal
