′�?, using a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−1 phonon corresponds on the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical theory computations exhibit that the residual absorption of your BGSe https://mylesiaoal.blogcudinti.com/32723468/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
