A thermodynamic and electrical conductivity study of nonstoichiometric cerium dioxide

Thermodynamic and dc electrical conductivity measurements were performed on nonstoichiometric CeO 2− x to characterize the electrical behavior and defect structure in the vicinity of the n to p transition. Using the mass action approach, activation energies of 2.57, 1.15 and 0.63 eV were obtained fo...

Description
Summary:Thermodynamic and dc electrical conductivity measurements were performed on nonstoichiometric CeO 2− x to characterize the electrical behavior and defect structure in the vicinity of the n to p transition. Using the mass action approach, activation energies of 2.57, 1.15 and 0.63 eV were obtained for the electron, hole and ionic partial conductivities respectively (600–1000°C, 1< P o 2
