Basic Semiconductor Equations
The mathematical model that describes semiconductor device physics consists
of a set of fundamental equations (derived from Maxwell’s laws), which link
together electrostatic potential and carriers densities:
Poisson’s equation
Continuity equation
Constitutive equation
It relates variations in electrostatic
potential to local charge densities.
They describe the way electron
and hole densities evolve as a
result of transport, generation, and
recombination processes.
