New kind of quantum transport discovered in a device combining high-temperature superconductors and graphene
(a) Schematic cross section of our device. GrΔ is superconducting graphene under BSCCO, Gr′ is a p-doped graphene, and Gr is native graphene. d is the length of Gr′. The dotted lines at either end of Gr′ denote the interfaces. (b) Optical micrograph of device A from Table 1. S is shorthand for BSCCO. The dotted white outline tags graphene. The red X and N1–N5 are contacts to graphene. C1–C4 are contacts to BSCCO. The scale bar is 10μm. Credit: Physical Review Letters (2023). DOI:…
