WHAT DOES BAGA4SE7 CRYSTAL MEAN?

′�?, that has a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds for the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical concept computations display which the residual absorption in the BGSe crystal
