We report on a method to fabricate and measure gateable molecular junctions
which 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
IV-characteristics at room temperature.
