Theory of polar domains in moiré heterostructures
Daniel Bennett
The discovery of unconventional ferroelectric behavior in twisted bilayers has prompted the consideration of moiré heterostructures as polar materials. However, misconceptions abou…
Electrically tunable stacking domains and ferroelectricity in moiré superlattices
Daniel Bennett, Benjamin Remez
It is well known that stacking domains form in moiré superlattices due to the competition between the interlayer van der Waals forces and intralayer elastic forces, which can be re…
Flexoelectric radial polarization of single-walled nanotubes from first-principles
Daniel Bennett
Flexoelectricity is the polar response of an insulator to strain gradients such as bending. While the size dependence of this effect makes it weak in bulk systems in comparison to…
Electrostatics and domains in ferroelectric superlattices
Daniel Bennett, Maitane Muñoz-Basagoiti, Emilio Artacho
The electrostatics arising in ferroelectric/dielectric two-dimensional heterostructures and superlatitices is revisited here within a simplest Kittel model, in order to define a cl…
