HELPING THE OTHERS REALIZE THE ADVANTAGES OF BAGA4SE7 CRYSTAL

′�?, that has 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 on the crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful idea computations clearly show the residual absorption of the BGSe crystal
