HELPING THE OTHERS REALIZE THE ADVANTAGES OF BAGA4SE7 CRYSTAL

′�?, using a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−one phonon corresponds into the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful concept computations present that the residual absorption of the BGSe crystal
