THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, with a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds into the crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional principle computations display the residual absorption on the BGSe crystal orig
