On-and-off chip cooling of a Coulomb blockade thermometer down to 2.8 mK
M. Palma, C. P. Scheller, D. Maradan +3
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 overc…
Traceable Coulomb Blockade Thermometry
Ossi Hahtela, Emma Mykkanen, Antti Kemppinen +6
We present a measurement and analysis scheme for determining traceable thermodynamic temperature at cryogenic temperatures using Coulomb blockade thermometry. The uncertainty of th…
Accurate Coulomb Blockade Thermometry up to 60 Kelvin
M. Meschke, A. Kemppinen, J. P. Pekola
We demonstrate experimentally a precise realization of Coulomb Blockade Thermometry (CBT) working at temperatures up to 60 K. Advances in nano fabrication methods using electron be…
Trapping hot quasi-particles in a high-power superconducting electronic cooler
H. Q. Nguyen, T. Aref, V. J. Kauppila +4
The performance of hybrid superconducting electronic coolers is usually limited by the accumulation of hot quasi-particles in the superconducting leads. This issue is all the more…
Metallic Coulomb Blockade Thermometry down to 10 mK and below
L. Casparis, M. Meschke, D. Maradan +5
We present an improved nuclear refrigerator reaching 0.3 mK, aimed at microkelvin nanoelectronic experiments, and use it to investigate metallic Coulomb blockade thermometers (CBTs…
Laterally proximized aluminum tunnel junctions
J. V. Koski, J. T. Peltonen, M. Meschke +1
This letter presents experiments on junctions fabricated by a new technique that enables the use of high quality aluminum oxide tunnel barriers with normal metal electrodes at low…
Ex-situ Tunnel Junction Process Technique Characterized by Coulomb Blockade Thermometry
M. Prunnila, M. Meschke, D. Gunnarsson +3
We investigate a wafer scale tunnel junction fabrication method, where a plasma etched via through a dielectric layer covering bottom Al electrode defines the tunnel junction area.…
Comparison of Coulomb Blockade Thermometers with the International Temperature Scale PLTS-2000
Matthias Meschke, Jost Engert, Dieter Heyer +1
The operation of the primary Coulomb blockade thermometer (CBT) is based on a measurement of bias voltage dependent conductance of arrays of tunnel junctions between normal metal e…
SQUIPT - Superconducting Quantum Interference Proximity Transistor
F. Giazotto, J. T. Peltonen, M. Meschke +1
We present the realization and characterization of a novel-concept interferometer, the superconducting quantum interference proximity transistor (SQUIPT). Its operation relies on t…
Quantized current of a hybrid single-electron transistor with superconducting leads and a normal-metal island
Antti Kemppinen, Matthias Meschke, Mikko Möttönen +2
We discuss the operation of the superconductor - insulator - normal-metal - insulator - superconductor (SINIS) turnstile. This voltage-biased hybrid single-electron transistor (SET…
