TOP GUIDELINES OF BAGA4SE7 CRYSTAL

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