Ambipolar Graphene Field Effect Transistors by Local Metal Side Gates [PDF]
, 2010 We demonstrate ambipolar graphene field effect transistors individually controlled by local metal side gates. The side gated field effect can have on/off ratio comparable with that of the global back gate, and can be tuned in a large range by the back ...
