WHAT DOES BAGA4SE7 CRYSTAL MEAN?

′�?, by using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−1 phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional theory computations present the residual absorption in the BGSe crystal o
