Abstract

This is a simple tool that demonstrates electron and hole density distributions based on the Fermi-Dirac and Maxwell Boltzmann equations. It shows the dependence of carrier density, densisty of states, and occupation factor on temperature and fermi level. Users can choose between doped and undoped semi-conductors. Silicon, Germanium, and GaAs can be studied as a function of doping or Fermi level and temperature.

Homework: The tool is supported by a homework assignment in which students are asked to explore the differences between Fermi-Dirac and Maxwell-Boltzmann distributions, compute electron and hole concentrations, study temperature dependences, and study freeze-out.
