This chapter demonstrates the application of the Wigner Monte Carlo simulator which has been discussed in the preceding chapters. The simulation of electrostatic lenses is presented in Section 6.1 along with investigations into the emerging field of quantum control of electron wavepackets. An application of electrostatic lenses to improve the performance of actual devices is demonstrated in Section 6.2. The calculation of a steady-state solution using 2D WMC simulation is shown, which presents a novel result that has been made possible by the optimized algorithms (Chapter 4) and the parallelization (Chapter 5) presented before.
