Inkjet-defined field-effect transistors from chemical vapour deposited graphene (2014)

Abstract In this work, inkjet printing methods are used to create graphene field effect transistors with mobilities up to 3000 cm2 V?1 s?1. A commercially-available chromium-based ink is used to define the device channel by inhibiting chemical vapour deposition of graphene in defined regions on a copper catalyst. We report on the patterned graphene growth using optical and electronic microscopy, Raman spectroscopy and X-ray photoelectron spectros- copy. Silver nanoparticle ink is used to create electrical contacts to the defined graphene regions. The resulting devices were characterised by electrical transport measurements at room temperature. As a result we are able to fabricate high-performance graphene field effect transistors entirely defined by a commercial inkjet printer with channel lengths of 50 lm.is
