THE ULTIMATE GUIDE TO BAGA4SE7 CRYSTAL

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