Unexpected Crystal and Domain Structures and Properties in Compositionally Graded PbZr1-xTixO3 Thin Films

Unexpected Crystal and Domain Structures and Properties in Compositionally Graded PbZr1-xTixO3 Thin Films

Synthesis of compositionally graded versions of PbZr1‐xTixO3 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...

Zusammenfassung:Synthesis of compositionally graded versions of PbZr1‐xTixO3 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.
