Chaotic front dynamics in semiconductor superlattices
A. Amann, J. Schlesner, A. Wacker +1
We analyze the dynamical evolution of the current and the charge density in a superlattice for fixed external dc voltage in the regime of self-sustained current oscillations, using…

Semiconductor Superlattices: A model system for nonlinear transport
Andreas Wacker
Electric transport in semiconductor superlattices is dominated by pronounced negative differential conductivity. In this report the standard transport theories for superlattices, i…

Transport in nanostructures: A comparison between nonequilibrium Green functions and density matrices
Andreas Wacker
Stationary electric transport in semiconductor nanostructures is studied by the method of nonequilibrium Green functions. In the case of sequential tunneling the results are compar…
