′�?, by using a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−one phonon corresponds for the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful principle computations show that the residual absorption of the BGSe https://actonb221qdp6.blogsvirals.com/profile
