- Band structure enters through the scattering rates (initial and final states) and through the dynamics (velocity, energy versus k).
- Different Levels of Approximations Used
- Non-parabolic multi-valley models based on k.p theory
- Full Band Monte Carlo
1) Density of States Model (Hichijo and Hess, Phys. Rev. B 23, 4197 (1981); Monte Carlo Device Simulation: Full Band and Beyond, (ed. K. Hess, Kluwer, 1991)
Assume scattering dominated by optical deformation potential scattering at high energy. Renormalize nonparabolic rates by actual density of states.
2) Full Anisotropic Scattering: Include full k-k? dependence (very time consuming)
