Kinetic and hydrodynamic models for simulation of carrier heating and
transport in bulk semiconductors and semiconductor devices are conside
red. In the framework of the kinetic approach based on the single-part
icle Monte Carlo simulation main attention is paid to the hydrodynamic
model parameters as well as to the time- and frequency-dependences of
the hot carrier linear response calculations. In the framework of the
hydrodynamic approach the drift velocity and mean energy conservation
equations are investigated under the single electron gas approximatio
n. Possible extensions as well as widely used simplifications of this
model such as the energy transport model, the local energy model, the
extended drift-diffusion formalism and the drift-diffusion approximati
on are considered.
