′�?, by using a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−1 phonon corresponds to your crystal IR absorption edge, instead of the residual absorption peak. Density practical idea computations clearly show the residual absorption from the BGSe https://baga4se7crystal29639.newsbloger.com/33062850/the-smart-trick-of-baga4se7-crystal-that-no-one-is-discussing
