Paper Abstract
The magnetic doping of Ge-QDs is highly coveted and has been pursued for several years. The Ge- Mn-Si substrate system presents a complex challenge, and the competition between dopant integration
and formation of silicides, germanides and metastable phases makes the magnetic doping a considerable,
and maybe insurmountable challenge. We will discuss the interaction of Mn with all growth surface,
Si(100), Ge(100) wetting layer, and Ge{105} QD facet, as well as the co-deposition of Mn and Ge. The
monoatomic Mn-wires, which form on Si(100), and their magnetic signatures allow unique insight into the relation between bonding and magnetism. We will close with an outlook on the feasibility of QD
manipulation by controlling dopant-surface interactions.
