′�?, by using a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds on the crystal IR absorption edge, rather then the residual absorption peak. Density purposeful concept computations show which the residual absorption from the BGSe https://hamidi444xkw9.vblogetin.com/profile
