Project A6
Impact of Nuclear Spin Cooling on Carrier Spin Coherence
This project investigates nuclear spin fluctuations, effects of quadrupole splitting of nuclear spin states, spin-lattice relaxation and decoherence in the nuclear spin system of semiconductors. For this purpose, the nuclear spin polarization will be enhanced by dynamic polarization via spin-oriented electrons. Optically detected magnetic resonance will be used to determine the evolution of the nuclear spins in magnetic fields and their back-action on the central electron spin of a localized charge carrier. The role of quadrupole splittings of nuclear spin states, which may considerably affect the nuclear-nuclear and electron-nuclear spin dynamics and carrier spin coherence, will also be studied.
