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…
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…
In situ engineering hexagonal boron nitride in van der Waals heterostructures with selective SF6 etching
Hitesh Agarwal, Antoine Reserbat-Plantey, David Barcons Ruiz +10
Van der Waals heterostructures are at the forefront in materials heterostructure engineering, offering the ultimate control in layer selectivity and capability to combine virtually…
Terahertz photocurrent probe of quantum geometry and interactions in magic-angle twisted bilayer graphene
Roshan Krishna Kumar, Geng Li, Riccardo Bertini +24
Moiré materials represent strongly interacting electron systems bridging topological and correlated physics. Despite significant advances, decoding wavefunction properties underly…
