摘要: Synthesis of compositionally graded versions PbZr(1-x)Ti(x)O3 thin films results in unprecedented strains (as large as ≈4.5 × 10(5) m(-1)) and correspondingly unexpected crystal structures, ferroelectric domain properties. This includes the observation built-in electric fields 200 kV/cm. Compositional strain gradients could represent a new direction strain-control materials.
