Engineering Three Dimensional Moiré Flat Bands
Lede Xian, Ammon Fischer, Martin Claassen +3
We demonstrate that the concept of moiré flat bands can be generalized to achieve electronic band engineering in all three spatial dimensions. For many two dimensional van der Waal…
Moiré heterostructures as a condensed matter quantum simulator
Dante M. Kennes, Martin Claassen, Lede Xian +7
Twisted van der Waals heterostructures have latterly received prominent attention for their many remarkable experimental properties, and the promise that they hold for realising el…
Universal moiré nematic phase in twisted graphitic systems
Carmen Rubio-Verdú, Simon Turkel, Larry Song +12
Graphene moiré superlattices display electronic flat bands. At integer fillings of these flat bands, energy gaps due to strong electron-electron interactions are generally observed…
Moiré metrology of energy landscapes in van der Waals heterostructures
Dorri Halbertal, Nathan R. Finney, Sai S. Sunku +20
The emerging field of twistronics, which harnesses the twist angle between two-dimensional materials, represents a promising route for the design of quantum materials, as the twist…
Graphene/-RuCl: An Emergent 2D Plasmonic Interface
Daniel J. Rizzo, Bjarke S. Jessen, Zhiyuan Sun +16
Work function-mediated charge transfer in graphene/-RuCl heterostructures has been proposed as a strategy for generating highly-doped 2D interfaces. In this geometry, graphe…
Nonlinear twistoptics at symmetry-broken interfaces
Kaiyuan Yao, Nathan R. Finney, Jin Zhang +17
Broken symmetries induce strong nonlinear optical responses in materials and at interfaces. Twist angle can give complete control over the presence or lack of inversion symmetry at…
Realization of Nearly Dispersionless Bands with Strong Orbital Anisotropy from Destructive Interference in Twisted Bilayer MoS2
Lede Xian, Martin Claassen, Dominik Kiese +4
Recently, the twist angle between adjacent sheets of stacked van der Waals materials emerged as a new knob to engineer correlated states of matter in two-dimensional heterostructur…
