Paper Title:
Theoretical Comparison of 3C-SiC and Si Nanowire FETs in Ballistic Regime
  Abstract

3C-SiC is a promising material for high power and high-speed electronic devices as well as in sensors operating at high temperatures or hostile environments. For these reasons, we solved self-consistently the Poisson equation within the quantum Non Equilibrium Green Function Formalism (NEGF) in order to model and compare 3C-SiC and Si nanowire (NW) Field Effect Transistors (FETs) operating in ballistic regime (at room temperature 300 K). As a general conclusion of our calculations, Si and SiC NW FETs have almost the same electrical behavior: they depict the same subthreshold slope and have similar on currents [ION/IOFF (SiC)~81 % ION/IOFF (Si) in case of 4 nm NW cross section side].
