Superlattice-Induced Insulating States and Valley-Protected Orbits in Twisted Bilayer Graphene
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 and interlayer hybridization effects. We report on electronic transport measurements of high mobility small angle TBLG devices showing clear evidence for insulating states at …
