THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, using a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−1 phonon corresponds into the crystal IR absorption edge, as opposed to the residual absorption peak. Density practical principle computations exhibit the residual absorption in the BGSe crystal originat
