We also plotted the experimentally calculated (in pink) and calculated (in black) values of phonon energies at ? point of such 9 phonon modes, for just a comparison, in Supplementary Fig. 12. In Desk 1, the first column reveals These modes??energies from distinct polarized Raman location. Each price will be the averages of peak fitting benefits f… Read More

Also, the dielectric operate is often expressed in terms of refractive index n, extinction coefficient k as follows13:Figure 3b–e shows the densities of state with the BGO with antisite defect, O vacancy, Bi vacancy and Ge vacancy respectively. The plots exhibit that the placement in the defect state induced is determined by the type of defect. … Read More
