Edge Contact to 2D materials

Electrically interfacing 3D metal electrodes to atomically thin 2D materials presents a fundamental technical challenge.~ Recently we demonstrated that metalizing along the 1D edge of graphene enables a new device topology with remarkably low contact resistance.~ Here we expand the capability of this edge-contact technique by integrating leads with complex properties, such as ferromagnetic and superconducting metals.~ Implications for realizing novel electronic behavior in 2D layered materials will be discussed. ~ ~[1] L.
