Query: Modeling of transport through submicron semiconductor structures: A
  direct solution to the Poisson-Boltzmann equations   We report on a computational approach based on the self-consistent solution
of the steady-state Boltzmann transport equation coupled with the Poisson
equation for the study of inhomogeneous transport in deep submicron
semiconductor structures. The nonlinear, coupled Poisson-Boltzmann system is
solved numerically using finite difference and relaxation methods. We
demonstrate our method by calculating the high-temperature transport
characteristics of an inhomogeneously doped submicron GaAs structure where the
large and inhomogeneous built-in fields produce an interesting fine structure
in the high-energy tail of the electron velocity distribution, which in general
is very far from a drifted-Maxwellian picture.
