THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, which has a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density functional theory computations clearly show which the residual absorption with the BGSe crystal o
