Metal contacts in carbon nanotube field-effect transistors: Beyond the Schottky barrier paradigm
Metal contacts in carbon nanotube field-effect transistors: Beyond the Schottky barrier paradigm
The observed performances of carbon nanotube field-effect transistors are examined using first-principles quantum transport calculations. We focus on the nature and role of the electrical contact of Au and Pd electrodes to open-ended semiconducting nanotubes, allowing the chemical contact at the surface to fully develop through large-scale relaxation of the …
