WHAT DOES BAGA4SE7 CRYSTAL MEAN?

′�?, by using a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional theory computations clearly show that the residual absorption of your BGSe cr
