Characterization of NbTiN films with thicknesses below 20 nm for low power kinetic inductance amplifiers
A. Giachero, M. R. Vissers, J. D. Wheeler +6
A quantum-limited amplification chain is a fundamental advantage for any application that may benefit from the detection of very faint signals. Reading out arrays of superconductin…
A Model for Excess Johnson Noise in Superconducting Transition-edge Sensors
Abigail Wessels, Kelsey Morgan, Daniel T. Becker +9
Transition-Edge Sensors (TESs) are two-dimensional superconducting films used to detect energy or power. TESs are voltage biased in the resistive transition where the film resistan…
Current distribution and transition width in superconducting transition-edge sensors
D. S. Swetz, D. A. Bennett, K. D. Irwin +2
Present models of the superconducting-to-normal transition in transition-edge sensors (TESs) do not describe the current distribution within a biased TES. This distribution is comp…
Insensitivity of sub-Kelvin electron-phonon coupling to substrate properties
Jason M. Underwood, Peter J. Lowell, Galen C. O'Neil +1
We have examined the role of the substrate on electron-phonon coupling in normal metal films of Mn-doped Al at temperatures below 1 K. Normal metal-insulator-superconductor junctio…
Andreev Reflections in Micrometer-Scale Normal-Insulator-Superconductor Tunnel Junctions
Peter J. Lowell, Galen C. O'Neil, Jason M. Underwood +1
Understanding the subgap behavior of Normal-Insulator-Superconductor (NIS) tunnel junctions is important in order to be able to accurately model the thermal properties of the junct…
Observations and modeling of large area normal-metal/insulator/superconductor refrigerator cooling from 300 mK to below 100 mK
Galen C. O'Neil, Peter J. Lowell, Jason M. Underwood +1
In a normal-metal/insulator/superconductor (NIS) tunnel junction refrigerator, the normal-metal electrons are cooled and the dissipated power heats the superconducting electrode. T…
