Suppression of electron relaxation and dephasing rates in quantum dots caused by external magnetic fields
V. N. Stavrou
An external magnetic field has been applied in laterally coupled dots (QDs) and we have studied the QD properties related to charge decoherence. The significance of the applied mag…
Electron Scattering and Hybrid Phonons in Low Dimensional Laser Structures made with GaAs/AlxGa1-xAs
V. N. Stavrou, G. P. Veropoulos
We theoretically and numerically present the hybrid phonon modes for the double heterostructure GaAs/AlxGa1-xAs and their interactions with electrons. More specifically, we have ca…
Semiconductor charge qubit relaxation due to two-phonon processes
V. N. Stavrou, Xuedong Hu
We theoretically study the relaxation of electron orbital states of a double quantum dot system due to two-phonon processes. In particular, we calculate how the relaxation rates de…
Charge decoherence in laterally coupled quantum dots due to electron-phonon interactions
V. N. Stavrou, Xuedong Hu
We investigate electron charge decoherence in a laterally-coupled single-electron semiconductor double quantum dot through electron-phonon interaction. We analytically and numerica…
Electronic structure of rectangular quantum dots
E. Räsänen, H. Saarikoski, V. N. Stavrou +3
We study the ground state properties of rectangular quantum dots by using the spin-density-functional theory and quantum Monte Carlo methods. The dot geometry is determined by an i…
