Abstract This paper investigates the output characteristics in tunnel field-effect transistor (TFET). The nonlinear current (NLC) in output characteristics has remained as a critical issue for operating at low drain bias (VDS). In this paper, the energy band diagrams and charge density distributions are analyzed to confirm the relation between output current and VDS, based on the technology computer-aided design (TCAD) simulations. Then, the NLC is analyzed as a channel potential pinning which occurs from the charges supplied from the drain to the channel.
