′�?, that has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds into the crystal IR absorption edge, rather then the residual absorption peak. Density useful theory computations clearly show the residual absorption of the BGSe https://annl665bpa0.lotrlegendswiki.com/user
