CONSIDERATIONS TO KNOW ABOUT BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds to your crystal IR absorption edge, instead of the residual absorption peak. Density purposeful principle computations exhibit the residual absorption in the BGSe crystal originates
