DETAILED NOTES ON BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, rather then the residual absorption peak. Density purposeful principle computations present that the residual absorption of your BGSe crystal orig
