THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

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