At submonolayer coverage, Mn forms atomic wires on the Si(001) surface oriented perpendicular to the underlying Si dimer rows. While many other elements form symmetric dimer wires at room temperature, we show that Mn wires have an asymmetric appearance and pin the Si dimers nearby. We find that an atomic configuration with a Mn trimer unit cell can explain these observations as due to the interplay between the Si dimer buckling phase near the wire and the orientation of the Mn trimer. We study…

Magnetism in Mn Nanowires and Clusters as {\delta}-doped Layers in Group IV Semiconductors (Si, Ge)

Mn doping of group-IV semiconductors (Si/Ge) is achieved by embedding a thin Mn-film as a {\delta}-doped layer in group-IV matrix. The Mn-layer consists of a dense layer of monoatomic Mn-wires, which
