Hybrid Electronic-Ionic Ferroelectricity in Superlubric van der Waals Heterostructures
Jing Huang, Jun Kang, Daniel Bennett
One strategy to lower the switching barrier in a sliding ferroelectric (sFE) is to insert an incommensurate spacer to reduce sliding friction, creating a superlubric sliding ferroe…

Stacking-engineered ferroelectricity and multiferroic order in van der Waals magnets
Daniel Bennett, Gabriel Martínez-Carracedo, Xu He +4
Two-dimensional (2D) materials that exhibit spontaneous magnetization, polarization or strain (referred to as ferroics) have the potential to revolutionize nanotechnology by enhanc…

Asymmetric dynamical charges in two-dimensional ferroelectrics
Daniel Bennett, Philippe Ghosez
Ferroelectricity is commonly understood in terms of dynamical charges, which represent the dipole moments generated by atomic displacements or the forces induced by electric fields…
