Title: Dynamic nuclear polarization in phosphorus doped silicon

Abstract: Nuclear spins in phosphorus doped silicon are promising candidates for quantum computing, metrology and sensing applications. An important technique for enabling these applications is Dynamic Nuclear Polarization (DNP), which involves cooling the nuclear spins faster and to lower effective temperatures compared to thermal relaxation to the lattice temperature. In this talk, I will present results from NMR investigations into an optical DNP process observed in the presence of above bandgap light and show how our approach also provides insight into bound exciton formation and Auger recombination dynamics.
