THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, using a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−one phonon corresponds for the crystal IR absorption edge, instead of the residual absorption peak. Density useful concept computations clearly show the residual absorption on the BGSe crystal origin
