Claim:
1. A graphene-based terahertz device comprising: a top graphene layer that is formed of 1 to 10 graphenes and has a first electrode deposited on one edge of the layer; a bottom graphene layer that is formed of 1 to 10 graphenes and has a second electrode deposited on one edge of the layer; and a liquid crystal layer or a piezocrystal layer, 1 to 1000 μm in thickness, disposed between the top graphene layer and the bottom graphene layer, wherein the first electrode and the second electrode are so aligned to prevent short circuit through the liquid crystal layer or the piezocrystal layer, and the top surface of the top graphene layer and the bottom surface of the bottom graphene layer are each covered by a layer of dielectric material.
