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…
