Abstract
Synthesis of compositionally graded versions of PbZr1-xTi xO3 thin films results in unprecedented strains (as large as ≈4.5 × 105 m-1) and correspondingly unexpected crystal structures, ferroelectric domain structures, and properties. This includes the observation of built-in electric fields in films as large as 200 kV/cm. Compositional and strain gradients could represent a new direction of strain-control of materials.
