THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

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