Abstract

The effects of strain on the phase transitions of BaTiO₃ nanowires taking into account three components of polarization are studied by thermodynamic analysis based on the Landau theory. Similar to the strain effect on phase transitions in thin films, the mismatch strain between the nanowire and substrate governs the Curie temperature. The complete misfit strain-temperature phase diagram shows six stable ferroelectric phases for BaTiO₃ nanowires under different strain and temperature conditions.
