Metal matrix nanocomposites (MMNCs) are gaining more and more interest because
matrices and nanophases with heterogeneous characteristics could combine to provide …

Quantum confinement and surface effects (SEs) dramatically modify most solid state
phenomena as one approaches the nanometer scale, and superconductivity is no …

Josephson junction parametric amplifiers have become essential tools for microwave
quantum circuit readout with minimal added noise. Even after improving at an impressive …

The development of the fundamental superconducting (SC) energy scales—the SC energy
gap Δ and the superfluid stiffness J—of granular aluminum, ie, thin films composed of …

We investigate thin films of conducting aluminium-oxide, also known as granular aluminium,
as a material for superconducting high quality, high kinetic inductance circuits. The films are …

We report on a detailed study of the optical response and T c-ρ phase diagram (T c being
the superconducting critical temperature and ρ the normal state resistivity of the film) of …

Microwave kinetic inductance detectors (MKIDs) are thin-film, cryogenic, superconducting
resonators. Incident Cooper pair-breaking radiation increases their kinetic inductance …

Granular aluminum is a promising material for high kinetic inductance devices such as qubit
circuits. It has the advantage over atomically disordered materials such as NbN x, to …

Recent advances in the experimental growth and control of disordered thin films,
heterostructures, and interfaces provide fertile ground for the observation and …

We present scanning tunneling microscope (STM) measurements of the local electronic
structure of superconducting granular aluminium films. The STM spectra show a …
