NOT KNOWN DETAILS ABOUT BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−one phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density purposeful principle computations exhibit that the residual absorption on the BGSe crystal ori
