Localized emission in MoSe monolayers on GaN nanopillars
Abderrahim Lamrani Alaoui, Ãlvaro Moreno, Maximilian Heithoff +12
Solid-state quantum emitters (QEs) in two-dimensional semiconductors offer compact, chip-compatible sources for quantum photonics. In transition-metal dichalcogenides (TMDs), nanop…
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…
Optical detection of charge defects near a graphene transistor using the Stark shift of fluorescent molecules
Carlotta Ciancico, Iacopo Torre, Bernat Terrés +7
Two-dimensional crystals and their heterostructures unlock access to a class of photonic devices, bringing nanophotonics from the nanometer scale down to the atomic level where qua…
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…
