HELPING THE OTHERS REALIZE THE ADVANTAGES OF BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−one phonon corresponds for the crystal IR absorption edge, as an alternative to the residual absorption peak. Density purposeful principle computations present which the residual absorption in the BGSe
