WHAT DOES BAGA4SE7 CRYSTAL MEAN?

′�?, having a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, instead of the residual absorption peak. Density practical principle computations present the residual absorption from the BGSe crystal originates
