THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, by using a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds to your crystal IR absorption edge, instead of the residual absorption peak. Density useful theory computations present the residual absorption on the BGSe crystal originates in
