2D–2D heterostructures are typically held together by van der Waals interactions. Now, an on-device MoS2–graphene heterostructure has been prepared that is covalently linked through a bifunctional molecule featuring a maleimide and a diazonium group. The electronic properties of the resulting heterostructure are shown to be dominated by the molecular interface.
