Abstract

We report on a method to fabricate and measure gateable molecular junctions that are stable at room temperature. The devices are made by depositing molecules inside a few-layer graphene nanogap, formed by feedback controlled electroburning. The gaps have separations on the order of 1–2 nm as estimated from a Simmons model for tunneling. The molecular junctions display gateable I–V-characteristics at room temperature.
