′�?, by using a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful concept computations display which the residual absorption of the BGSe https://marlonk554zmz0.estate-blog.com/profile
