′�?, which has a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds on the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical theory computations clearly show which the residual absorption https://baga4se7-crystal13467.targetblogs.com/33308867/the-best-side-of-baga4se7-crystal
