Nanoscale periodic domain patterns in tetragonal ferroelectrics: A phase-field study
Ananya Renuka Balakrishna, John E. Huber, Ingo Münch
Ferroelectrics form domain patterns that minimize their energy subject to imposed boundary conditions. In a linear, constrained theory, that neglects domain wall energy, periodic d…
Nanoscale domain patterns and a concept for an energy harvester
Ananya Renuka Balakrishna, John E. Huber
The current work employs a phase-field model to test the stability of nanoscale periodic domain patterns, and to explore the application of one pattern in an energy harvester devic…
Scale effects and the formation of polarization vortices in tetragonal ferroelectrics
Ananya Renuka Balakrishna, John E. Huber
Vortices consisting of quadrant domains are rarely observed in ferroelectrics. Although experiments show polarization flux closures with stripe domains, it is as yet unc…
Nano-actuator concepts based on ferroelectric switching
Ananya Renuka Balakrishna, John E. Huber, Chad M. Landis
The concept of a nano-actuator that uses ferroelectric switching to generate enhanced displacements is explored using a phase-field model. The actuator has a ground state in the ab…
