′�?, using a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful concept computations show the residual absorption of the BGSe crystal originates https://kevinc725svt1.atualblog.com/profile
