Impact of dielectric properties on ionic conductivity of Ce0.9Sm0.1O1.95 via defect interaction

This study mainly investigates the defect interaction mediated ionic conductivity of Ce0.9Sm0.1O1.95. The ionic conductivity mainly depends on the concentration of free oxygen vacancies. The formed oxygen vacancies are bounded with dopant cations due to columbic interaction which depends on the diel...
