The structural and electrical properties of samarium doped ceria films formed by e-beam deposition technique

The best ionic conductivity σtot = 1.66 Sm− 1 at 873 K temperature, activation energy ΔEa = 0.87 eV (σg = 1.66 Sm− 1, σgb = 1.66 Sm− 1) was achieved when 2 Å/s deposition rate was used. The grain size (in the formed SDC thin films) was ~ 83 nm in this case.
