′�?, having a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−one phonon corresponds into the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful principle computations demonstrate the residual absorption on the BGSe crystal originates https://keikoz703kmn9.life3dblog.com/profile
