Magic-angle twisted bilayer graphene (MATBG) combines in one single material different phases such as insulating, metallic, and superconducting. These phases and their in situ tunability make MATBG an important platform for the fabrication of superconducting devices. We realize a split-gate-defined geometry which enables us to tune the width of a superconducting channel formed in MATBG.

AbstractMagic-angle twisted bilayer graphene can host a variety of gate-tunable correlated states – including superconducting and correlated insulator states. Recently, junction-based superconducting moiré devices have been introduced, enabling the study of the charge, spin and orbital nature of superconductivity, as well as the coherence of moiré electrons in magic-angle twisted bilayer graphene.
