nanoHUB.org: online simulations and more

This tool is based on the ballistic transport in CNTs which are believed to have scattering lengths in excess of a hundred nanometers. Features such as the Schottky barriers (SBs) at the source/drain (S/D) contacts, band-to-band tunneling (BTBT) current, and ambipolar conduction are condsidered in this tool.

Thanks to Samuel Chang for his contributions in code optimization.
