A scalable non-superconducting tunnel junction technology
Juho Luomahaara, Kristupas Razas, Omid Sharifi Sedeh +15
Tunnel junctions are one of the key elements of chip-scale microsystems serving various technologies from classical microelectronics to quantum information. Aluminium and its oxide…
Magnetic Field-Enhanced Graphene Superconductivity with Record Pauli-Limit Violation
Jixiang Yang, Omid Sharifi Sedeh, Chiho Yoon +22
Spin-polarized superconductors offer a rare platform for studying electronic correlations, but few candidate systems have been experimentally confirmed to date. Here, we report the…
Family of Unconventional Superconductivities in Crystalline Graphene
Junseok Seo, Armel A. Cotten, Mingchi Xu +17
Unconventional superconductors exhibit multiple broken symmetries and exceed the range of the Bardeen-Cooper-Schrieffer (BCS) theory. For instance, time-reversal symmetry can be br…
Signatures of Chiral Superconductivity in Rhombohedral Graphene
Tonghang Han, Zhengguang Lu, Zach Hadjri +20
Chiral superconductors are unconventional superconducting states that break time reversal symmetry spontaneously and typically feature Cooper pairing at non-zero angular momentum.…
