Optical Investigation on Ultra Pure 28Si:P

Donor bound electron spins in an isotopically enriched 28Si:P matrix exhibit ultra-long spin coherence at low temperatures, due to non-existing nuclear spin of the host material, resulting in a suppression of the hyperfine interaction.

We investigate optically the addressability, optical selection rules and coherence time of the donor bound electrons in this material system.

Beside standard methods such as photoluminescence and Hanle-depolarization, we will employ semiconductor spin noise spectroscopy. As a long-term goal, the possibility of entanglement of two solid state systems as a potential quantum-repeater based on 28Si:P will be inspected.
