Sr2Ti7O14, a new phase, is synthesized by leveraging the innate chemical and thermodynamic instabilities in the SrTiO3–TiO2 system and non‐equilibrium growth techniques. The chemical composition, epitaxial relationships, and orientation play roles in the formation of this novel layered phase, which, in turn, possesses unusual charge ordering, anti‐ferromagnetic ordering, and low, glass‐like thermal...
We report pyroelectric emission from thin films of crystalline PbZr0.8Ti0.2O3 (PZT) on nanometer-sharp tips. The epitaxial PZT films are 30 nm thick and grown directly on batch fabricated single-crystal silicon tips. Pyroelectric emission occurs for heating rates ≥ 50 °C/min in a 20 V/μm external field, and for electric field strengths ≥ 6.7 V/μm when heated at 100 °C/min. The emitted electric charge...
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...
We report field emission from nanometer-sharp tips of polarized PbZr0.2Ti0.8O3 (PZT) and silicon. The ferroelectric PZT emitters are a high-density array of single-crystal silicon tips that are coated with a 30 nm thick film of crystalline PZT in a batch fabrication process. The PZT emitter tips begin to emit electrons at fields as low as 2 V/μm and reach threshold emission at fields as low as 3.9...
