Superconductivity on the Edge (IMAGE) DOE/US Department of Energy Caption Electrical conductance for molybdenum ditelluride. The image shows two modes, one with a dark red profile on the material’s edge, one with a bright red/yellow profile in the material’s bulk. These modes arise from different superconducting currents.
