Abstract
An electron device having a channel layer made of graphene is disclosed. The electron device includes a graphene layer on a substrate, and a source electrode, a drain electrode, and a gate insulating film on the graphene layer. The electron device further includes a first gate electrode on the gate insulating film between the source electrode and the drain electrode, and a second gate electrode within the substrate. For the second gate electrode, another gate insulating film is on the graphene layer, or alternatively, a part of the substrate is interposed between the second gate electrode and the channel layer.
