Orientation engineering is a universal strategy for ferroelectric trans-switching
Cameron Scott, Jorge Íñiguez-González
About two decades ago, ``strain engineering'' emerged as a powerful strategy to tune epitaxial thin films. Here we contend that ''orientation engineering'' - that is, controlling t…
Harnessing electrostatics through temperature modulations to control ferroelectrics
Cameron A. M. Scott, Xabier Diaz de Cerio, Jorge Íñiguez-González
Temperature modulations provide an alternative method for dynamically controlling the ferroelectric state. In this paper, we use scale-independent Landau potentials and predictive…
Alternative origins of polarity in compressively strained SrTiO3-RENiO3 capacitors
Evgenios Stylianidis, Panagiotis Koutsogiannis, Alexander Lione +8
Since its original prediction 25 years ago, room-temperature out-of-plane ferroelectricity in compressively strained SrTiO3 remains an ongoing pursuit. In this work, we investigate…
A GPU-based Solver for Polarization Dynamics in Ferroelectric Materials
Ali Hasan, Edoardo Piccolo, Anna Giordano +4
Ferroelectric materials can be used for the development of multiple device concepts combining non-volatility, small dimensions, low-power actuation, and electrical tunability. Such…
Machine learning Landau free energy potentials
Mauro Pulzone, Natalya S. Fedorova, Hugo Aramberri +1
We show how to construct Landau-like free energy potentials using a machine-learning approach. For concreteness, we focus on perovskite oxide PbTiO. We work with a training s…
