′�?, using a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds to the crystal IR absorption edge, in lieu of the residual absorption peak. Density purposeful concept computations demonstrate which the residual absorption of your BGSe https://baga4se7crystal17272.pages10.com/baga4se7-crystal-can-be-fun-for-anyone-68212344
