What Does BaGa4Se7 Crystal Mean?
′�?, which has a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density functional theory computations show which the residual absorption of your BGSe crystal origi
