′�?, with a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−1 phonon corresponds into the crystal IR absorption edge, rather then the residual absorption peak. Density useful theory computations exhibit that the residual absorption of your BGSe crystal https://johni544xtq9.topbloghub.com/profile
