WHAT DOES BAGA4SE7 CRYSTAL MEAN?

′�?, which has a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, in lieu of the residual absorption peak. Density purposeful theory computations display that the residual absorption from the BGSe crystal or
