Ultra-low-temperature scanning tunnelling spectroscopy measurements indicate that twisting the layers in heterostructures making up a single layer of superconducting NbSe2 on graphene leads to momentum-dependent changes in the superconducting gap. This ability could enable the development of artificial superconductors with nontrivial magnetic and topological properties.
