Direct view of gate-tunable miniband dispersion in graphene
superlattices near the magic twist angle
Superlattices from twisted graphene mono- and bi-layer systems give rise to on-demand quantum many-body states such as Mott insulators, unconventional superconductors and the fractional quantum Hall effect. These phenomena are observed in transport experiments when changing the filling of the low-energy electronic bands. Their origin is broadly ascribed to a …
