Study of electronic transport in tunnelling devices using an incoherent superposition of time dependent wave packets

The authors present an exhaustive study of the possibilities of studying electronic transport in tunnelling devices in terms of time dependent wave packets and Bohm trajectories. They point out how this approach provides dynamic information (not contained in the Hamiltonian eigenstates) which can be of great importance in studying nonequilibrium carrier dynamics in high speed-semiconductor devices. A preliminary implementation of their approach to studying real RTD devices is presented, and the technical viability and the possibilities of modeling local scattering within this approach are discussed.
