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…
Flat and tunable moire phonons in twisted transition-metal dichalcogenides
Alejandro Ramos-Alonso, Benjamin Remez, Daniel Bennett +2
Displacement fields are one of the main tuning knobs employed to engineer flat electronic band dispersions in twisted van der Waals multilayers. Here, we show that electric fields…
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…
Pseudo-proper two-dimensional electron gas formation
Daniel Bennett, Pablo Aguado-Puente, Emilio Artacho +1
In spite of the interest in the two-dimensional electron gases (2DEGs) experimentally found at surfaces and interfaces, important uncertainties remain about the observed insulator-…
