We also plotted the experimentally calculated (in crimson) and calculated (in black) values of phonon energies at ? position of those 9 phonon modes, for just a comparison, in Supplementary Fig. 12. In Desk 1, the initial column demonstrates These modes??energies from unique polarized Raman placing. Each and every price is the averages of peak fi… Read More

Also, the dielectric purpose could be expressed regarding refractive index n, extinction coefficient k as follows13:Determine 3b–e demonstrates the densities of point out for that BGO with antisite defect, O vacancy, Bi vacancy and Ge vacancy respectively. The plots present which the placement of the defect point out induced is dependent upon th… Read More
