CONSIDERATIONS TO KNOW ABOUT BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical theory computations display which the residual absorption on the BGSe crystal originates
