DAMOCLES is a self-consistent Poisson/Monte Carlo computer program simulating electronic transport in semiconductor devices.

Transport of charge carriers (electrons and/or holes) is treated using an ensemble Monte Carlo algorithm to solve the Boltzmann transport equation. The kinematics (free flights) and dynamics (scattering) are modeled using the band-structure of the semiconductors obtained from empirical pseudopotentials calculations.
A two-dimensional Poisson solver is used to calculate the electrostatic potential self-consistently with the Monte Carlo charge distribution. Devices of arbitrary geometry, realistic doping profiles, and a variety of cubic and zinc-blend semiconductors can be simulated.

• Overviews provides a quick introduction to DAMOCLES: why it was created, which physical models it employs, what are Monte Carlo methods.
• Physics illustrates with a few examples how 'basic physics' can be applied to understand basic issues of charge transport in semiconductors (the determination of the scattering rates in Si, the calculation of the effective mobility in Si channels, the simulation of electron injection into silicon dioxide, of sub-band-gap ionization in small Si FETs, and the comparison of the performance of ultrasmall FETs based on various semiconductors.
• Devices illustrates the capability of the program from a pure device perspective, showing examples relative to Si n-channel and p-channel MOSFETs, SOIs, double-gate Si FETs, and GaAs/InGaAs HEMTs
