Elemental Topological Insulator with a Tunable Fermi Level: Strained α-Sn on InSb(001)
A. Barfuss, L. Dudy, M. R. Scholz +16
We report on the epitaxial fabrication and electronic properties of a topological phase in strained α-Sn on InSb. The topological surface state forms in the presence of an unusual…
Structural Examination of Au/Ge(001) by Surface X-Ray Diffraction and Scanning Tunneling Microscopy
S. Meyer, T. Umbach, C. Blumenstein +7
The one-dimensional reconstruction of Au/Ge(001) was investigated by means of autocorrelation functions from surface x-ray diffraction (SXRD) and scanning tunneling microscopy (STM…
Symmetry-Breaking Phase Transition without Peierls Mechanism in Conducting Monoatomic Chains
C. Blumenstein, J. Schaefer, M. Morresi +3
The one-dimensional (1D) model system Au/Ge(001), consisting of linear chains of single atoms on a surface, is scrutinized for lattice instabilities predicted in the Peierls paradi…
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…
Self-organized atomic nanowires of noble metals on Ge(001): atomic structure and electronic properties
J. Schaefer, S. Meyer, C. Blumenstein +9
Atomic structures of quasi-one-dimensional (1D) character can be grown on semiconductor substrates by metal adsorption. Significant progress concerning study of their 1D character…
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…
