′�?, which has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds towards the crystal IR absorption edge, as an alternative to the residual absorption peak. Density purposeful principle computations display which the residual absorption from https://baga4se7crystal06283.blogpixi.com/33006061/examine-this-report-on-baga4se7-crystal
