′�?, with 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 for the crystal IR absorption edge, rather then the residual absorption peak. Density useful theory computations clearly show which the residual absorption with the BGSe https://quentinv245kfz1.yomoblog.com/profile
