Influence of the charge carrier tunneling processes on the recombination dynamics in single lateral quantum dot molecules

C. Hermannstädter, G. J. Beirne, M. Witzany +7

We report on the charge carrier dynamics in single lateral quantum dot molecules and the effect of an applied electric field on the molecular states. Controllable electron tunnelin…

Heterogeneous confinement in laterally coupled InGaAs/GaAs quantum dot molecules under lateral electric fields

Jie Peng, Claus Hermannstädter, Marcus Witzany +7

We study the electronic and optical properties of laterally coupled InGaAs/GaAs quantum dot molecules under lateral electric field. We find that electrons perceive the double-dot s…

Violation of non-interacting -representability of the exact solutions of the Schrödinger equation for a two-electron quantum dot in a homogeneous magnetic field

M. Taut, P. Machon, H. Eschrig

We have shown by using the exact solutions for the two-electron system in a parabolic confinement and a homogeneous magnetic field [ M.Taut, J Phys.A{\bf 27}, 1045 (1994) ] that bo…

Theory of vortex states in magnetic nanodisks with induced Dzyaloshinskii-Moriya interactions

A. B. Butenko, A. A. Leonov, A. N. Bogdanov +1

Vortex states in magnetic nanodisks are essentially affected by surface/interface induced Dzyaloshinskii-Moriya interactions. Within a micromagnetic approach we calculate the equil…
