HELPING THE OTHERS REALIZE THE ADVANTAGES OF BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−one phonon corresponds to your crystal IR absorption edge, rather than the residual absorption peak. Density useful principle computations exhibit that the residual absorption from the BGSe crystal or
