Abstract

Suspended poly(methyl methacrylate) (PMMA)/graphene microstamps can be site-specifically printed to any targeted position using a micromanipulator. The surface-enhanced Raman spectrum, gate-voltage-dependent conductance, half-integer quantum Hall effect, and electrical interconnection are investigated. Advantages of the technique include precise positioning, avoiding extrinsic doping effect, maintaining the graphene quality, improving the efficiency of chemical vapor deposition (CVD) grown graphene deployment, and convenient device repair.
