Massive Dirac Fermions and Hofstadter Butterfly in a van der Waals Heterostructure

Graphene, Gapped and Butterflied The remarkable transport properties of graphene, such as the high electron mobility, make it a promising material for electronics. However, unli...

van der Waals Heterostructures with High Accuracy Rotational Alignment

We describe the realization of van der Waals (vdW) heterostructures with accurate rotational alignment of individual layer crystal axes. We illustrate the approach by demonstrat...

Tunable moiré bands and strong correlations in small-twist-angle bilayer graphene

Significance Accurately controlled, very long wavelength moiré patterns are realized in small-twist-angle bilayer graphene, and studied using electron transport and scanning pro...

Superlattice-Induced Insulating States and Valley-Protected Orbits in Twisted Bilayer Graphene

Twisted bilayer graphene (TBLG) is one of the simplest van der Waals heterostructures, yet it yields a complex electronic system with intricate interplay between moiré physics a...
