′�?, with a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds on the crystal IR absorption edge, as opposed to the residual absorption peak. Density practical concept computations demonstrate that the residual absorption in the BGSe https://zalmayy111pco5.bloguerosa.com/profile
