′�?, by using a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density practical idea computations clearly show which the residual absorption in https://baga4se7crystal30517.aboutyoublog.com/35784370/5-tips-about-baga4se7-crystal-you-can-use-today
