Polar-vortex-driven interfacial strain coupling in PbTiO3/SrRuO3 Heterostructures
S. A. Raza, V. A. Stoica, H. Zheng +7
Interfacial coupling in oxide heterostructures is a central problem in condensed-matter physics, as it typically emerges at the atomic scale through local interactions mediated by…
A Dynamical Phase-Field Model for the Optical Properties of Ferroelectrics
Aiden Ross, Anya Frazer, Venkatraman Gopalan +1
Ferroelectric materials are promising platforms for controllable photonic devices because of the strong coupling between their spontaneous polarization and optical properties. Yet,…
Anomalous Piezoelectricity from Polarization-Dependent Electrostriction in Wurtzites
Guo-Dong Zhao, Aiden Ross, Yueze Tan +3
The piezoelectric coefficient is a third-rank tensor connecting the strain or stress with the electric field or polarization, whereas the electrostriction coefficient is a fourth-r…
Emergence of millimeter-wave resonances in self-assembled ferroelectric metamaterials
Florian Bergmann, Peter Meisenheimer, Aiden Ross +26
Resonators are a key component in modern communications and computing. As demand and technological advances push component requirements into the terahertz regime, there is signific…
Breaking symmetry to create a parallel-plate varactor dielectric with unparalleled microwave performance
Florian Bergmann, Matthew R. Barone, Zishen Tian +24
Voltage-tunable capacitors (varactors) are key to microwave circuits. Tunable dielectric varactors outperform competing technologies in almost every relevant metric but usually suf…
