Bandwidth-Limited Critical Currents in Electrically Tunable Moiré Bands
Riccardo Bertini, Xueqiao Wang, Sergey Slizovskiy +16
Moiré superlattices host narrow minibands whose bandwidth governs correlated and topological phases. Here, we demonstrate that the bandwidth also sets the critical current for the…
Evolution of the Berry curvature dipole in uniaxially strained bilayer graphene
Karel Cuypers, Robin Smeyers, Bert Jorissen +1
While in pristine bilayer graphene the Berry curvature dipole (BCD), a necessary ingredient for the nonlinear anomalous Hall effect, is zero, uniaxial strain can give rise to finit…
Single-photon detection enabled by negative differential conductivity in moiré superlattices
Krystian Nowakowski, Hitesh Agarwal, Sergey Slizovskiy +19
Detecting individual light quanta is essential for quantum information, space exploration, advanced machine vision, and fundamental science. Here, we introduce a novel single photo…
Machine-Learning Interatomic Potential for Twisted Hexagonal Boron Nitride: Accurate Structural Relaxation and Emergent Polarization
Wilson Nieto Luna, Robin Smeyers, Cem Sevik +2
The emerging ferroelectric properties of two-dimensional (2D) heterostructures are at the forefront of science and prospective technology. In moiré bilayers, twisting or heterostru…
Elastic Screening of Pseudogauge Fields in Graphene
Christophe De Beule, Robin Smeyers, Wilson Nieto Luna +2
Lattice deformations in graphene couple to the low-energy electronic degrees of freedom as effective scalar and gauge fields. Using molecular dynamics simulations, we show that the…
Strong gate-tunability of flat bands in bilayer graphene due to moiré encapsulation between hBN monolayers
Robin Smeyers, Lucian Covaci, Milorad V. Milošević
When using hexagonal boron-nitride (hBN) as a substrate for graphene, the resulting moiré pattern creates secondary Dirac points. By encapsulating a multilayer graphene within alig…
