Scanning tunneling spectroscopy of superconducting nitridized aluminum thin films
Jose Antonio Moreno, Pablo García Talavera, Alba Torras-Coloma +5
Nitride-based superconductors represent a family of superconducting thin film materials displaying higher quality than their corresponding bare superconductor when used in devices…
Superinductor-based ultrastrong coupling in a superconducting circuit
Alba Torras-Coloma, Luca Cozzolino, Ariadna Gómez-del-Pulgar-Martínez +2
We present an ultrastrong superinductor-based coupling consisting of a flux qubit galvanically coupled to a resonator. The coupling inductor is fabricated in granular Aluminum, a s…
Magnetic penetration depth of Aluminum thin films
David López-Núñez, Alba Torras-Coloma, Queralt Portell Montserrat +5
We present a study of the superconducting penetration depth in aluminum thin films of varying thickness. The range of thicknesses chosen spans from the thin-film regime to the…
Superconducting nitridized-aluminum thin films
Alba Torras-Coloma, Leyre Martínez de Olcoz, Eva Céspedes +6
We report the direct observation of superconductivity in nitridized-aluminum thin films. The films are produced by sputtering deposition of aluminum in a controlled mixture of nitr…
