Dominant role of the shear strain induced admixture in spin-flip processes in self-assembled quantum dots
Adam Mielnik-Pyszczorski, Krzysztof Gawarecki, Michał Gawełczyk +1
We study theoretically the spin-flip relaxation processes for a single electron in a self-assembled InAs/GaAs quantum dot, using an 8-band kp theory in the envelope function approx…
Spin-orbit coupling and magnetic field dependence of carriers states in a self-assembled quantum dot
Krzysztof Gawarecki
In this work I investigate the influence of spin-orbit coupling on the magnetic field dependence of carrier states in a self-assembled quantum dot. I calculate the hole energy leve…
Controllable electron spin dephasing due to phonon state distinguishability in a coupled quantum dot system
Michał Gawełczyk, Mateusz Krzykowski, Krzysztof Gawarecki +1
We predict a spin pure dephasing channel in electron relaxation between states with unequal Zeeman splittings, exemplified by a spin-preserving electron tunneling between quantum d…
Accuracy of effective mass equation for a single and double cylindrical quantum dot
A. Mielnik-Pyszczorski, K. Gawarecki, P. Machnikowski
In this contribution we study the accuracy of various forms of electron effective mass equation in reproducing spectral and spin-related features of quantum dot systems. We compare…
Limited accuracy of conduction band effective mass equations for semiconductor quantum dots
Adam Mielnik-Pyszczorski, Krzysztof Gawarecki, Paweł Machnikowski
Effective mass equations are the simplest models of carrier states in a semiconductor structures that reduce the complexity of a solid-state system to Schrödinger- or Pauli-like eq…
Polaron resonances in two vertically stacked quantum dots
Paweł Karwat, Krzysztof Gawarecki, Paweł Machnikowski
In this work, we present a theoretical study of polaron states in a double quantum dot system. We present realistic calculations which combine 8 band \kp model, configuration inter…
