NOT KNOWN FACTUAL STATEMENTS ABOUT BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds on the crystal IR absorption edge, rather then the residual absorption peak. Density useful concept computations display which the residual absorption with the BGSe crystal or
