Abstract :
Specific contact resistivities of source/drain contacts employing interfacial layers are calculated with simulations of tunneling transport. Fermi level depinning, dipoles, and other techniques for barrier lowering are explored. Interfacial materials with the potential to meet future contact resistivity requirements are identified for silicon and high-mobility alternatives.
