Abstract

Taking advantage of the "coffee-ring" effect, graphene electrodes with channel lengths as low as 1-2 micrometers are patterned by inkjet printing. Organic thin film transistors and complementary inverters are also fabricated using these graphene electrodes and show excellent performance.

Keywords: coffee-ring effect; complementary inverter; graphene; inkjet printing; organic thin film transistors.
