′�?, using a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−one phonon corresponds to your crystal IR absorption edge, rather than the residual absorption peak. Density practical concept computations exhibit that the residual absorption of the BGSe crystal https://baga4se7crystal40481.liberty-blog.com/32836867/5-easy-facts-about-baga4se7-crystal-described
