Intraband tunneling
WebIn this paper, we present a computationally efficient full-band method to determine the current characteristics of circular, gate-all-around nanowire (NW) FETs in the sub-10-nm regime. The well-established top-of-the-barrier model is extended to consider intraband tunneling through the Wentzel-Kramers-Brillouin approximation.
