An all-carbon-based field effect transistor (FET) was fabricated on flexible polyethylene terephthalate substrates by the aerosol jet printing method described in this paper. Three different types of homogeneous conductive inks were made and then printed layer-by-layer to form the FET chips. The conducting-reduced graphene oxide was used as electrodes (source and drain) and channel, respectively. Graphene oxide was used as dielectrics while multi-walled carbon nanotubes acted as the gate electrode. The all-carbon-based FET shows a good mobility of 350 cm2 (V s)-1 at a drain bias of -1 V. This simple and novel method explores a promising way to fabricate all-carbon-based, flexible and low-cost electronic devices. © 2013 IOP Publishing Ltd.
