Bloch oscillations in superlattice simulated by the Monte Carlo method

The Monte Carlo based semiclassical model for the vertical electron transport in superlattice including most important features of electron transport through the superlattice minibands is presented. Inelastic acoustic phonon, polar optical phonon and ionized impurity scattering are considered in the bulk formalism. The model has been applied on GaAs/GaAlAs superlattice simulation with one miniband for gamma electrons. The simulation is performed by different conditions defined by temperature, electric field and ionized impurity concentration. Bloch oscillations of miniband electrons with different lifetimes, frequencies and amplitudes are observed in the simulation results.
