′�?, having a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds to the crystal IR absorption edge, instead of the residual absorption peak. Density functional idea computations exhibit the residual absorption from the BGSe crystal originates https://baga4se7-crystal62849.rimmablog.com/32046162/baga4se7-crystal-can-be-fun-for-anyone
