Abstract
We have begun to explore the possibility of thin film three dimensional (3D) topological insulator (TI) based tunnel FETs (TFETs), specifically Bi2Se3 here, using quantum ballistic transport simulations with a tight-binding Hamiltonian in the atomic orbital basis including spin degrees of freedom. TI-based TFETs would be analogous in some ways to graphene nanoribbon TFETs, but without the sensitivity to ribbon width and edge roughness, and in some ways to narrow gap III-V TFETs but with substantially thinner quantum well widths.
