Interfacial ferroelectricity in marginally twisted 2D semiconductors
Astrid Weston, Eli G Castanon, Vladimir Enaldiev +19
Twisted heterostructures of two-dimensional crystals offer almost unlimited scope for the design of novel metamaterials. Here we demonstrate a room-temperature ferroelectric semico…
Atomic reconstruction in twisted bilayers of transition metal dichalcogenides
Astrid Weston, Yichao Zou, Vladimir Enaldiev +17
Van der Waals heterostructures form a massive interdisciplinary research field, fueled by the rich material science opportunities presented by layer assembly of artificial solids w…
Infrared-to-violet tunable optical activity in atomic films of GaSe, InSe, and their heterostructures
Daniel J. Terry, Viktor Zólyomi, Matthew Hamer +11
Two-dimensional semiconductors - atomic layers of materials with covalent intra-layer bonding and weak (van der Waals or quadrupole) coupling between the layers - are a new class o…
Probing hotspots of plasmon-enhanced Raman scattering by nanomanipulation of carbon nanotubes
Sebastian Heeg, Nick Clark, Aravind Vijayaraghavan
We present a two-step procedure to probe hotspots of plasmon-enhanced Raman scattering with carbon nanotubes. Dielectrophoretic deposition places a small carbon nanotube bundle on…
Quantum Nature of Plasmon-Enhanced Raman Scattering
Patryk Kusch, Sebastian Heeg, Christian Lehmann +6
We report plasmon-enhanced Raman scattering in graphene coupled to a single plasmonic hotspot measured as a function of laser energy. The enhancement profiles of the G peak show st…
Optical-phonon resonances with saddle-point excitons in twisted-bilayer graphene
Ado Jorio, Mark Kasperczyk, Nick Clark +4
Twisted-bilayer graphene (tBLG) exhibits van Hove singularities in the density of states that can be tuned by changing the twisting angle . A -defined tBLG has been produced…
