5 EASY FACTS ABOUT BAGA4SE7 CRYSTAL DESCRIBED

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