  • Many features of a superconductor are encoded in the Josephson effect and understanding changes at the local level can help explain related phenomena. Here, the authors use scanning tunnelling microscopy to study local changes in the Josephson effect and how they relate to the transport channel configuration.

  • The tunnelling current in scanning tunnelling spectroscopy has often been treated by a continuous charge flow, which lacks proper treatment of charge quantization. Here, Ast et al. unveil the effects of granularity in the tunnelling current at extremely low temperatures by including P(E) theory, thereby reaching the quantum limit in scanning tunnelling spectroscopy.
