DEMONs simulates electron transport through one-dimensional DEvices by the MONte Carlo technique. The program produces histograms of the carrier distribution function at different positions as well as other quantities of interest such as the average electron velocity, carrier density, and total and kinetic energy. While DEMON was originally written for the ternary Al(x)Ga(1-x)As, this version has been expanded to treat Ga(x)In(1-x)As, Al(x)In(1-x)As, and even conventional Si devices as well. Additional capabilities include the ability to compute the impulse response of devices.

Results for III-V materials are computed by DEMON 2.0, developed by Martin Klausmeier-Brown, Chris Maziar, and Paul Dodd. Results for Si are computed by SDEMON, developed by Mark Stettler.


Thanks to Steve Clark, and Mark Lundstrom for helping to design and debug the Rappture interface.
