′�?, that has a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional principle computations clearly show that the residual absorption on https://baga4se7crystal19517.yomoblog.com/39272617/top-guidelines-of-baga4se7-crystal
