′�?, using a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds to your crystal IR absorption edge, instead of the residual absorption peak. Density functional idea computations exhibit the residual absorption of your BGSe crystal originates https://ingmara578spk5.dailyhitblog.com/profile
