WebMar 3, 2024 · The appearance of localized supercurrents at the edges of a Josephson junction is generally attributed to the topology of the electronic band structure and edge states. (1) Edge states and the accompanying edge currents are typically found in ultraclean systems such as 2D electron gases, (2) nanowires, (3) and graphene.
