′�?, by using a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional concept computations exhibit which the residual absorption from https://henryg813hfb3.vblogetin.com/profile
