Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
Quasiparticle spectroscopy in technologically-relevant niobium using London penetration depth measurements
Sunil Ghimire, Kamal R. Joshi, Amlan Datta +10
London penetration depth was measured in niobium foils, thin films, single crystals, and superconducting radio-frequency (SRF) cavity pieces cut out from different places. The low-…
Two-Level Systems in Nucleated and Non-Nucleated Epitaxial alpha-Tantalum films
L. D. Alegria, D. M. Tennant, K. R. Chaves +4
Building usefully coherent superconducting quantum processors depends on reducing losses in their constituent materials. Tantalum, like niobium, has proven utility as the primary s…
Characterization of Nb films for superconducting qubits using phase boundary measurements
Kevin M. Ryan, Carlos G. Torres-Castanedo, Dominic P. Goronzy +8
Continued advances in superconducting qubit performance require more detailed understandings of the many sources of decoherence. Within these devices, two-level systems arise due t…
Quasiparticle spectroscopy, transport, and magnetic properties of Nb films used in superconducting transmon qubits
Kamal R. Joshi, Sunil Ghimire, Makariy A. Tanatar +10
Niobium thin films on silicon substrate used in the fabrication of superconducting qubits have been characterized using scanning and transmission electron microscopy, electrical tr…
Anisotropic superconductivity of niobium based on its response to non-magnetic disorder
Makariy A. Tanatar, Daniele Torsello, Kamal R. Joshi +8
Niobium is one of the most studied superconductors, both theoretically and experimentally. It is tremendously important for applications, and it has the highest superconducting tra…
