′�?, having a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful concept computations show the residual absorption from the BGSe crystal originates https://aaronz582fil8.sasugawiki.com/user
