′�?, which has a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as an alternative to the residual absorption peak. Density useful concept computations clearly show the residual absorption of https://brooksvvsqo.idblogz.com/33184110/5-easy-facts-about-baga4se7-crystal-described
