Giant atomic swirl in graphene bilayers with biaxial heterostrain
F. Mesple, N. R. Walet, G. Trambly de Laissardière +7
The study of moiré engineering started with the advent of van der Waals heterostructures in which stacking two-dimensional layers with different lattice constants leads to a moiré…
Observation of Kekulé vortices induced in graphene by hydrogen adatoms
Y. Guan, C. Dutreix, H. Gonzales-Herrero +5
Fractional charges are one of the wonders of the fractional quantum Hall effect, a liquid of strongly correlated electrons in a large magnetic field. Fractional excitations are als…
Elastic properties of moiré lattices in epitaxial two-dimensional materials
Alexandre Artaud, Nicolas Rougemaille, Sergio Vlaic +3
Unlike conventional two-dimensional (2D) semiconductor superlattices, moiré patterns in 2D materials are flexible and their electronic, magnetic, optical, and mechanical properties…
Heterostrain rules the flat-bands in magic-angle twisted graphene layers
F. Mesple, A. Missaoui, T. Cea +5
The moiré of twisted graphene bilayers can generate flat bands in which charge carriers do not posses enough kinetic energy to escape Coulomb interactions with each other leading t…
Measuring the Berry phase of graphene from wavefront dislocations in Friedel oscillations
C. Dutreix, H. González-Herrero, I. Brihuega +3
Electronic band structures dictate the mechanical, optical and electrical properties of crystalline solids. Their experimental determination is therefore of crucial importance for…
Electronic spectrum of twisted graphene layers under heterostrain
L. Huder, A. Artaud, T. Le Quang +5
We demonstrate that stacking layered materials allows a novel type of strain engineering where each layer is strained independently, which we call heterostrain. We combine detailed…
