Reasons for formation of depressed semicircle in solid electrolyte?

I have done EIS of SDC (Sm doped ceria) electrolyte from 550 to 750C. I observed the formation of a depressed semicircle. Also the diameter of semicircle decreases with increasing temperature with...

Oxygen vacancy generation in Raman spectroscopy?

If Ceria is separately doped with Sm and Li, which one will generate more oxygen vacancies and why? And if Ceria is co-doped with Sm and Li (Ce0.8Sm2-xLixO2, x=0, 0.05, 0.10, 0.15, 0.20), which...

How can I calculate concentration of individual species in my sample through Raman spectra?

I have prepared mixed metal oxide sample by co-doping cerium with Sm and Mg through co-precipitation route using Na2CO3 as precipitating agent. I annealed my sample at low temperature i.e. 600 C....
