5 SIMPLE TECHNIQUES FOR BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds on the crystal IR absorption edge, rather than the residual absorption peak. Density useful theory computations show the residual absorption in the BGSe crystal originates with th
