Coulomb effects in tunneling through a quantum dot stack
H. Sprekeler, G. Kiesslich, A. Wacker +1
Tunneling through two vertically coupled quantum dots is studied by means of a Pauli master equation model. The observation of double peaks in the current-voltage characteristic in…
Positive Correlations in Tunneling through coupled Quantum Dots
H. Sprekeler, G. Kiesslich, A. Wacker +1
Due to the Fermi-Dirac statistics of electrons the temporal correlations of tunneling events in a double barrier setup are typically negative. Here, we investigate the shot noise b…
Theoretical analysis of spectral gain in a THz quantum cascade laser: prospects for gain at 1 THz
S. -C. Lee, A. Wacker
In a recent Letter [Appl. Phys. Lett. 82, 1015 (2003)], Williams et al. reported the development of a terahertz quantum cascade laser operating at 3.4 THz or 14.2 meV. We have calc…
Coulomb scattering with remote continuum states in quantum dot devices
R. Wetzler, A. Wacker, E. Sch"oll
Electron capture and emission by Coulomb scattering in self-assembled quantum dot (QD) devices is studied theoretically. While the dependence of the Coulomb scattering (Auger) rate…
Shot noise of coupled semiconductor quantum dots
G. Kiesslich, A. Wacker, E. Schoell
The low-frequency shot noise properties of two electrostatically coupled semiconductor quantum dot states which are connected to emitter/collector contacts are studied. A master eq…
A hybrid model for chaotic front dynamics: From semiconductors to water tanks
A. Amann, K. Peters, U. Parlitz +2
We present a general method for studying front propagation in nonlinear systems with a global constraint in the language of hybrid tank models. The method is illustrated in the cas…
