′�?, that has a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−one phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density practical idea computations exhibit that the residual absorption of your https://kylerttqlf.bloggip.com/32688263/baga4se7-crystal-an-overview
