Large Scale Graphene Transistor Arrays

(started in fall 2009 and will be resumed and completed in spring 2011)

Graphene, a single atomic sheet of carbon atoms, was recently isolated by separating single layers of graphite and received tremendous interest in electronic applications. The widely used mechanical exfoliation method used to obtain single layers of graphene, however, is uncontrolled and not useful for manufacturing large scale electronics. We will explore various contact printing methods for producing large scale graphene transistor arrays. The goal of this project is to achieve few layer or single layer graphene transistor arrays on centimeter size silicon wafer with high yield.
