A SIMPLE KEY FOR BAGA4SE7 CRYSTAL UNVEILED

′�?, having a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−1 phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density useful theory computations clearly show the residual absorption of your BGSe crystal originates wi
