Abstract

Researchers fabricated high-quality cobalt-substituted BiFeO3 epitaxial thin films with monoclinic distortions and systematically examined the relationship between the polarization directions and the piezoelectric responses. They demonstrate that polarization rotation played a crucial role in improving piezoelectric responses in this material. This conclusion was applied to the BiFeO3 -system and general piezoelectric materials including PbZr1-xTixO3 (PZT).
