NEW STEP BY STEP MAP FOR BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful principle computations demonstrate the residual absorption on the BGSe crystal orig
