THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, with a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds on the crystal IR absorption edge, rather then the residual absorption peak. Density useful concept computations display the residual absorption in the BGSe crystal originates through
