Abstract

Resonant tunnelling structures are receiving attention as a testbed for theoretical approaches to quantum transport. We present a Wigner function study of a double quantum barrier resonant tunnelling device formed by layers of AlGaAs in GaAs. Our study deals with the influence of the boundary conditions on the initial distribution as well as on the time-evolution of the system. We use a Gaussian wave packet to study the numerical effects of the boundaries. We attempt to solve the system in both the time-evolution and steady-state cases, including self-consistency in the potential.
