′�?, that has a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−one phonon corresponds into the crystal IR absorption edge, rather then the residual absorption peak. Density purposeful theory computations exhibit the residual absorption of your BGSe crystal https://aivenz581ded4.madmouseblog.com/profile
