While regular flat bands are good for enhancing the density of states and hence the gap,
they are detrimental to the superfluid weight. We show that the predicted nontrivial topology …

Berry curvature is analogous to magnetic field but in momentum space and is commonly
present in materials with nontrivial quantum geometry. It endows Bloch electrons with …

Moiré patterns are quasi‐periodic geometric patterns generated by the incommensurate
stacking between two monolayers; they have rapidly attracted enormous attention due to …

Van der Waals heterostructures display numerous unique electronic properties. Nonlocal
measurements, wherein a voltage is measured at contacts placed far away from the …

Moiré superlattice patterns at the interface of two-dimensional (2D) van der Waals (vdW)
materials, arising from a small displacement between similar lattices, have been extensively …

Twist-controlled moiré superlattices (MSs) have emerged as a versatile platform for realizing
artificial systems with complex electronic spectra. The combination of Bernal-stacked bilayer …

This paper presents our findings on the recursive band gap engineering of chiral fermions in
bilayer graphene doubly aligned with hBN. Using two interfering moiré potentials, we …

Bubbles at the interface of two-dimensional layered materials in van der Waals
heterostructures cause deterioration in the quality of materials, thereby limiting the size and …

The superlattice obtained by aligning a monolayer graphene and boron nitride (BN) inherits
from the hexagonal lattice a sixty degrees periodicity with the layer alignment. It implies that …

We report on the observation of Coulomb drag between graphene-hexagonal boron nitride
(h-BN) moiré heterostructure with a moiré wavelength of∼ 14 nm and an intrinsic graphene …
