NOT KNOWN DETAILS ABOUT BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds into the crystal IR absorption edge, instead of the residual absorption peak. Density useful principle computations present that the residual absorption from the BGSe crystal orig
