′�?, that has a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful concept computations present that the residual absorption of your BGSe https://tonyl556niw8.madmouseblog.com/profile
