Spin relaxation in quantum dots
Results are given for spin relaxation in quantum dots due to acoustic phonon-assisted flips of single spins at low temperatures. The dominant spin relaxation processes for varying dot size, temperature, and magnetic field are identified. These processes are mediated by the spin-orbit interaction and are described within a generalized effective mass treatment. Particular attention is given to ph...
متن کاملCoherence and Spin in GaAs Quantum Dots
This thesis describes a number of experiments performed in quantum dots as well as 2D systems fabricated in GaAs/AlGaAs 2D electron gases. The focus of the studies is set on spin, coherence and interaction effects of electrons in mesoscopic structures. Experiments investigating the rich physics of spin-orbit coupling in confined structures in presence of magnetic fields both perpendicular and p...
