nanoHUB.org: online simulations and more

The application was originally written in Matlab by Andres Godoy at University of Granada, Spain, and later rappturized by Hyung-Seok Hahm at University of Illinois at Urbana-Champaign.

It generates both quantum mechanical and classical electrostatic simulation results in a cross section (perpendicular to the transport direction) for two dimensional (2D) Trigate structures.

2D Poisson and Schroedinger equations are self-consistenly solved for this kind of devices. The user can select the dimensions of the silicon width (WSi), height (HSi), the gate oxide thickness (Tox) and the buried oxide thickness (TBox), and the applied gate voltage (Vg).

Other important simulation conditions are

- Room temperature: 300K
- Metal Gate Work Function: 4.61(eV)
- Substrate Doping: Na=1.0e12 Nd=1.0e10
- Orientation of a plane for the oxide interface and the cross-section: 100

The current version provides the following results:

- Classical Electron Density
- Classical Potential Distribution
- Quantum Electron Density
- First 6 Wavefunction Distribution
