CONSIDERATIONS TO KNOW ABOUT BAGA4SE7 CRYSTAL

′�?, with a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds on the crystal IR absorption edge, instead of the residual absorption peak. Density practical principle computations display the residual absorption of your BGSe crystal originates
