Article Synopsis
- The text discusses how magnetic impurities on superconducting surfaces create resonances called YSR states, which are linked to the behavior of superconducting pairs.
- These resonances exhibit a periodic pattern around impurities but often have wavelengths too short to be detected with standard techniques like scanning tunneling microscopy (STM).
- The authors improve imaging by using a CO molecule with a superconducting cluster on an STM tip, allowing for the visualization of complex interference patterns from YSR states that were previously undetectable, enhancing our understanding of superconductivity at the atomic level.
Step edges of topological crystalline insulators can be viewed as predecessors of higher-order topology, as they embody one-dimensional edge channels embedded in an effective three-dimensional electronic vacuum emanating from the topological crystalline insulator. Using scanning tunneling microscopy and spectroscopy, we investigate the behavior of such edge channels in PbSnSe under doping. Once the energy position of the step edge is brought close to the Fermi level, we observe the opening of a correlation gap.
