WHAT DOES BAGA4SE7 CRYSTAL MEAN?

′�?, having a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds towards the crystal IR absorption edge, instead of the residual absorption peak. Density functional principle computations demonstrate that the residual absorption from the BGSe crys
