THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, by using a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds on the crystal IR absorption edge, rather then the residual absorption peak. Density useful theory computations clearly show the residual absorption in the BGSe crystal originat
