Abstract

A Monte Carlo solution to the Boltzmann transport equation is used to simulate hot-carrier relaxation and transport in a unipolar superlattice base transistor. Simulated results show that, due to the reduced density of states and wavefunction overlap, interminiband scattering is suppressed and high-energy transport is maintained in the superlattice base longer than in a bulk base region. However, an increased probability of reverse scattering and a lower magnitude of velocity along the superlattice axis result in a reduced transfer ratio across the superlattice base.
