Abstract
A Topological INsulator-based field-effect transistor (TINFET) is disclosed. The TINFET includes a first and second gate dielectric layers separated by a topological insulator (TI) layer. A first gate contact is connected to the first gate dielectric layer on the surface that is opposite the TI layer. A second gate contact may be connected to the second gate dielectric layer on the surface that is opposite the TI layer. A first TI surface contact is connected to one surface of the TI layer, and a second TI surface contact is connected to the second surface of the TI layer.
