Abstract:
Disclosed is a graphene switching device having a tunable barrier. The disclosed graphene switching device includes a first electrode and an insulating layer which are respectively arranged in a first region and a second region which are separated from each other on a conductive semiconductor substrate, a graphene layer which is extended from the insulating layer to the first electrode on the substrate and is separated from the first electrode, a second electrode which faces the insulating layer on the graphene layer, a gate electrode above the graphene layer, and a first well which has a region of the substrate which touches the lower part of the graphene layer which is doped with impurity. The first wall has an energy barrier which is between the graphene layer and the first electrode.
