Moiré bands in twisted double-layer graphene

Web30 mrt. 2024 · Twisted double bilayer graphene (TDBG), on the other hand, is also likely to possess a flat band and display correlated phenomena. It is known that monolayer … WebIn this paper, we develop a continuum theory of the moiré minibands that are formed in the valence bands of Γ -valley homobilayers by a small relative twist. Our effective theory is benchmarked against large-scale ab initio electronic structure calculations that account for lattice relaxation.
