THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, using a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−1 phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density functional concept computations display which the residual absorption of the BGSe crystal originat
