′�?, with a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density purposeful idea computations show which the residual absorption on the BGSe crystal https://irvingi935rrn7.aboutyoublog.com/profile
