The smart Trick of BaGa4Se7 Crystal That Nobody is Discussing

′�?, with a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds to the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional idea computations clearly show the residual absorption from the BGSe crystal originates
