Nanosecond Thermometry with Josephson Junctions

Autor: Konrad Norowski, Matthias Meschke, Alexander Savin, Marek Foltyn, Jukka P. Pekola, M. Zgirski

Publikováno v: PHYSICAL REVIEW APPLIED. 10(4):1-11

We demonstrate a novel approach to thermometry at the nanoscale exploiting a superconducting weak link. Such a weak link probed with nanosecond current pulses serves as a temperature sensing element and, due to the fast inherent dynamics, is capable

Publikováno v: Hahtela, O, Mykkänen, E, Kemppinen, A, Meschke, M, Prunnila, M, Gunnarsson, D, Roschier, L, Penttilä, J & Pekola, J 2017, ' Traceable Coulomb blockade thermometry ', Metrologia, vol. 54, no. 1, pp. 69-76 . https://doi.org/10.1088/1681-7575/aa4f84

We present a measurement and analysis scheme for determining traceable thermodynamic temperature at cryogenic temperatures using Coulomb blockade thermometry. The uncertainty of the electrical measurement is improved by utilizing two sampling digital

On-and-off chip cooling of a Coulomb blockade thermometer down to 2.8 mK

Autor: Mario Palma, D. Maradan, Christian Scheller, Matthias Meschke, A. V. Feshchenko, Dominik M. Zumbühl

Publikováno v: APPLIED PHYSICS LETTERS. 111(25):1-5

Cooling nanoelectronic devices below 10 mK is a great challenge since thermal conductivities become very small, thus creating a pronounced sensitivity to heat leaks. Here, we overcome these difficulties by using adiabatic demagnetization of \emph{bot

Publikováno v: PHYSICAL REVIEW APPLIED. 3(1):1-7

We demonstrate radiofrequency thermometry on a micrometer-sized metallic island below 100 mK. Our device is based on a normal metal-insulator-superconductor tunnel junction coupled to a resonator with transmission readout. In the first generation of

Physical Review Letters, American Physical Society, 2017, 119 (7), pp.077701. ⟨10.1103/PhysRevLett.119.077701⟩

We report on combined measurements of heat and charge transport through a single-electron transistor. The device acts as a heat switch actuated by the voltage applied on the gate. The Wiedemann-Franz law for the ratio of heat and charge conductances

Nanosized Electronic Cooler Combined with Superconducting Proximity Effect Thermometry

Autor: Matthias Meschke

Publikováno v: Journal of Low Temperature Physics. 175:838-849

Electronic coolers have the potential to lower the temperature of mesoscopic electronic systems well below the lattice temperature with the final goal to reach ultimately an electronic temperature in the 10 mK range. A challenging task is to design a
