Graphene Films: Solution-Processed Ultrathin Chemically Derived Graphene Films as Soft Top Contacts for Solid-State Molecular Electronic Junctions (Adv. Mater. 10/2012)

Authors


Abstract

Nondestructive fabrication of solid-state molecular junctions using ultrathin chemically derived graphene films as soft top-contacts and protection layers is described by K. Nørgaard, B. W. Laursen, and co-workers on page 1333. The graphene is placed on top of a layer of short conjugated molecules or alkanethiols, protecting it during deposition of a gold top-contact on the layer. Chemically derived graphene can also act as a conductive interconnection between junctions in series, having molecular features such as non-linear charge-transport properties and molecular length dependence of the junction resistance.
