THE ULTIMATE GUIDE TO BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−1 phonon corresponds on the crystal IR absorption edge, as opposed to the residual absorption peak. Density useful idea computations exhibit which the residual absorption with the BGSe crystal originate
