THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, with a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density useful principle computations present that the residual absorption of the BGSe crystal orig
