The basic equations are the Poisson
equation and continuity equations for electrons and holes.
|div( . grad )
||= q . (n - p - C)
||= q . R +
||= - q . R +
The unknown quantities of this equation system are the electrostatic potential
and the electron and hole concentrations n and p, respectively.
C denotes the net concentration of the ionized impurities,
dielectric permittivity of the semiconductor, and R is the net recombination
rate which has to be modeled properly.
