Novel superconducting effects in multiterminal Josephson junctions, Part 1

摘要: We present comprehensive transport measurements of multiterminal graphene Josephson junctions. We have previously found that the coupling between different pairs of contacts results in nontrivial distribution of supercurrent across the device. Here, we isolate supercurrent mediated entirely by continuum contributions with energies above the superconducting gap. We also characterize the superconducting behaviors induced by out-of-plane magnetic fields and RF radiation.* Transport measurements conducted by EGA and TL were supported by Division of Materials Sciences and Engineering, Office of Basic Energy Sciences, US Department of Energy, under Award No. DE-SC0002765. EGA, AS and LZ performed lithographic fabrication and characterization of the samples with the support of NSF awards ECCS-1610213 and DMR-1743907. GF was supported under ARO Award W911NF16-1-0122.
