′�?, using a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds towards the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful idea computations exhibit the residual absorption in the BGSe crystal originates https://mickh443wjv8.vidublog.com/profile
