Spin Dynamics of Excitons in GaAs/AlGaAs Superlattices in a Magnetic Field
SAINT PETERSBURG STATE UNIV (RUSSIA) INST OF PHYSICS
Pagination or Media Count:
Kinetics of resonance luminescence of GaAs AlGaAs-superlattices in circular and linear polarizations is studied in a magnetic field of up to 5 T. Quantum beats of the luminescence are detected and their nature is identified. The energy and phase relaxation rates of excitons spins are determined from the experimental data.
