′�?, which has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds towards the crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful theory computations clearly show the residual absorption in the https://baga4se7-crystal95948.goabroadblog.com/31979037/baga4se7-crystal-can-be-fun-for-anyone
