Insensitivity of Sub-Kelvin Electron-Phonon Coupling to Substrate Properties

December 16, 2011

Jason M. Underwood, Peter J. Lowell, Galen C. O'Neil, Joel N. Ullom

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 junctions were used to measure the electron temperature in thin metal films as a

Andreev Reflections in Micrometer-Scale Normal Metal-Insulator-Superconductor Tunnel Junctions

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 junctions. Hekking and Nazarov developed a theory in which the NIS sub gap
