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…
Terahertz oscillation of domain walls in ferroelectric membranes
Xiangwei Guo, Jiaxuan Wu, Yujie Zhu +5
A fundamentally intriguing yet not well understood topic in the field of ferroelectrics is the collective excitation of domain walls (DWs), with potential applications to DW-based…
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…
Quantum Saturation of the Electro-Optic Effect
Aiden Ross, Sankalpa Hazra, Albert Suceava +4
Future quantum computing architectures require electro-optic materials that maintain a strong, stable performance at cryogenic temperatures. In conventional electro-optic materials…
Theory of terahertz pulse transmission through ferroelectric nanomembranes
Yujie Zhu, Aiden Ross, Xiangwei Guo +3
An analytical model is developed to predict the temporal evolution of the lattice polarization in ferroelectric nanomembranes upon the excitation by a terahertz (THz) electromagnet…
