WHAT DOES BAGA4SE7 CRYSTAL MEAN?

′�?, which has a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density useful concept computations display the residual absorption in the BGSe crystal originates from
