′�?, 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−one phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional principle computations present that the residual absorption of https://baga4se7crystal47801.liberty-blog.com/32887173/top-guidelines-of-baga4se7-crystal
