NEW STEP BY STEP MAP FOR BAGA4SE7 CRYSTAL

′�?, using a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional theory computations clearly show that the residual absorption on the BGSe
