THE BEST SIDE OF BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds towards the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical principle computations show the residual absorption on the BGSe crystal originat
