THE BEST SIDE OF BAGA4SE7 CRYSTAL

′�?, using a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds on the crystal IR absorption edge, as opposed to the residual absorption peak. Density useful principle computations display that the residual absorption on the BGSe crystal orig
