HELPING THE OTHERS REALIZE THE ADVANTAGES OF BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density purposeful principle computations display that the residual absorption with the BGSe cry
