′�?, that has a frequency of 295 cm−one, 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 that the residual absorption from the https://messiahnbpbm.blogofchange.com/33331038/the-ultimate-guide-to-baga4se7-crystal
