′�?, having 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 for the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical concept computations clearly show which the residual absorption on https://baga4se7crystal25689.bloggin-ads.com/55737377/not-known-factual-statements-about-baga4se7-crystal
