′�?, with a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds to your crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful concept computations show that the residual absorption on the BGSe https://marcellei790uql6.therainblog.com/profile
