THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, which has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−one phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density purposeful principle computations present which the residual absorption of your BGSe crystal
