Noncovalent Self‐Assembled Monolayers on Graphene as a Highly Stable Platform for Molecular Tunnel Junctions

Monolayer graphene is used as the bottom electrode to fabricate stable and high-quality self-assembled monolayer (SAM)-based tunnel junctions. The SAMs are formed on graphene via noncovalent bonds without altering the structure of the graphene. This work paves the way to new types of molecular electronic junctions based on 2D materials.
