′�?, by using a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−1 phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density practical idea computations exhibit which the residual absorption in the https://baga4se7-crystal73826.aboutyoublog.com/35605397/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
