Ferroelectric rods with adjustable dielectric tunability

Abstract

The polarization, dielectric constant, and tunability of a radial-loaded ferroelectric rod inside a highly pressurized polyethylene tube are calculated for both macro- and nanodimensions within a thermodynamic model. All studied properties, including the Curie temperature, are found to vary substantially by the applied load. The authors’ results indicate that many properties of the ferroelectric rod, including its tunability, can be optimized in this design by adjusting the applied pressure.
