Simulation of non-equilibrium electron transport in silicon quantum wires
- 76 Downloads
The Simulation of the non-equilibrium behavior of the charge transport in semiconductor devices is usually based on a coupling of the semiclassical Boltzmann transport equation with the Poisson equation. We follow this successful approach but extend it with the Schrödinger effective mass equation leading to a Schrödinger-Poisson-Boltzmann system for the description of the non-equilibrium electron transport in silicon quantum wires. The silicon quantum wire is joined with a substrate, so that the phonons are non-confined. We take into account zero- and first order intra- and intervalley scattering mechanisms.
