of pinhole free, low-κ
dielectric thin films on graphene is described for the first time.
Specifically, we demonstrate the heterogeneous electrochemical polymerization
of phenol to form thin (3–4 nm) layers of poly(phenylene oxide)
(PPO) on monolayer graphene samples prepared by micromechanical exfoliation
and chemical vapor deposition growth. We demonstrate the reliability
of depositing PPO films simultaneously on a large number of devices,
and selected individual graphene flakes/devices. The performance of
top-gated field effect transistor devices described herein demonstrates
the utility of electrodeposited PPO films as a top-gate dielectric.
