Illinois Tools: Effect of Doping on Semiconductors
01 Feb 2008 | Teaching Materials | Contributor(s): Umberto Ravaioli, Nahil Sobh
This Java applet allows students to visualize the effects of doping on carrier concentration in bulk silicon. It utilizes the non-degenerate Maxwell statistics to explore the effects of doping and temperature on carrier concentration and the energy band diagram.
Developed in conjunction with Kent Choquette's course ECE 398 at the University of Illinois at Urbana-Champaign.

Quantum Corrections for Monte Carlo Simulation
05 Jan 2006 | Online Presentations | Contributor(s): Umberto Ravaioli
Size quantization is an important effect in modern scaled devices. Due to the cost and limitations of available full quantum approaches, it is appealing to extend semi-classical simulators by adding corrections for size quantization. Monte Carlo particle simulators are good candidates, because a quantum correction potential may simply be added to the standard solution for Poisson equation, with minimal changes in the algorithms. This talk will review and compare the various approaches available for quantum corrections in Monte Carlo simulation. Representative results will include MOS capacitors and ultra-scaled structures like double-gate MOSFET and FinFET.
