A SIMPLE KEY FOR BAGA4SE7 CRYSTAL UNVEILED

′�?, with a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−one phonon corresponds to your crystal IR absorption edge, as opposed to the residual absorption peak. Density practical concept computations clearly show which the residual absorption from the BGSe crystal
