Abstract

The effects of misfit strain on the electrocaloric (EC) properties of BaTiO₃ thin films arestudied by using the Landau-Devonshire thermodynamic theory. The misfit-strain temperature phase diagrams for different electric fields are constructed. It was found that the EC effect of a BaTiO₃ thin film is strongly dependent on misfit strain. More interestingly, we found that BaTiO₃ thin films with tensile misfit strain exhibit a sizable EC effect in a wider temperature range in comparison with those with compressive misfit strain.
