http://www.freepatentsonline.com/8164089.html

This patent from Xerox teaches a variation of organic thin film transistors using graphene to increase the carrier mobility and improve switching speeds. Claim 1 reads:

1. A thin-film transistor comprising

a semiconducting layer, the semiconducting layer comprising an organic semiconductor and graphene;

wherein the graphene concentration in the semiconducting layer is lower than the critical concentration for a percolation network.
