Abstract
We propose a Klein tunneling transistor based on the geometrical optics of DFs. We consider the case of a prismatic active region generated by a triangular gate. In this region, total internal reflection may occur, which leads to the controllable suppression of transistor transmission. We study the transmission and the current in this device by means of non-equilibrium Green´s function (NEGF) simulation.
