Inelastic Transport in Carbon Nanotube Electronic and Optoelectronic Devices
28 Jun 2013 | Papers | Contributor(s): Siyu Koswatta
Discovered in the early 1990's, carbon nanotubes (CNTs) are found to have exceptional physical characteristics compared to conventional semiconductor materials, with much potential for devices surpassing the performance of present-day electronics. Semiconducting CNTs have large carrier mobilities and a direct electronic bandgap, resulting in enhanced band-to-band tunneling (BTBT) as well as optical properties that could lead to novel electronic and optoelectronic applications. Therefore, …

Ballistic transport in carbon nanotube metal-oxide-semiconductor field-effect transistors (CNT-MOSFETs) is simulated using the Non-equilibrium Green’s function formalism. A cylindrical transistor geometry with wrapped-around gate and doped source/drain regions are assumed. It should be noted that this code does NOT treat Schottky-barrier CNTFETs.
