′�?, using a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as opposed to the residual absorption peak. Density practical theory computations display that the residual absorption of your BGSe https://johng147ttu1.vblogetin.com/profile
