Evidence for Long-Range Spin Order Instead of a Peierls Transition in Si(553)-Au Chains
J. Aulbach, J. Schaefer, S. C. Erwin +5
Stabilization of the Si(553) surface by Au adsorption results in two different atomically defined chain types, one of Au atoms and one of Si. At low temperature these chains develo…
Magnetic-Order Induced Spectral-Weight Redistribution in a Triangular Surface System
Gang Li, Philipp Höpfner, Jörg Schäfer +6
The Sn-induced surface reconstruction on Si(111) has been investigated by material-specific many-body calculations and by angle-resolved photoelectron spectr…
Strictly One-Dimensional Electron System in Au Chains on Ge(001) Revealed By Photoelectron K-Space Mapping
S. Meyer, J. Schaefer, C. Blumenstein +5
Atomic nanowires formed by Au on Ge(001) are scrutinized for the band topology of the conduction electron system by k-resolved photoemission. Two metallic electron pockets are obse…
Renormalization of Bulk Magnetic Electron States at High Binding Energies
A. Hofmann, X. Y. Cui, J. Schaefer +11
The quasiparticle dynamics of electrons in a magnetically ordered state is investigated by high-resolution angle-resolved photoemission of Ni(110) at 10 K. The self-energy is extra…
