Twisted bilayer graphene2023 Elsevier B.V.Large lattice constant of Moire superlattice formed in twisted bilayer graphene enables observing Landau levels splitting into Hofstadter butterflies. This is expected for homogeneous bias conditions but its robustness against spatial potential fluctuations is left ...
The unusual properties of superconductivity in magic-angle twisted bilayer graphene (MATBG) have sparked considerable research interest1–13. However, despite the dedication of intensive experimental efforts and the proposal of several possible pairing m

twisted bilayer graphene with twist angles <2°. Nanoscale spatial fluctuations in twist angle and uniaxial heterostrain were statistically evaluated, revealing the prevalence of short-range disorder in moiré heterostructures. By quantitatively mapping strain tensor fields, we uncovered two regimes of ...
