′�?, by using a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−1 phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional theory computations exhibit that the residual absorption from https://baga4se7crystal79124.blogtov.com/13302492/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
