Characterizing cryogenic amplifiers with a matched temperature-variable noise source
Slawomir Simbierowicz, Visa Vesterinen, Joshua Milem +7
We present a cryogenic microwave noise source with a characteristic impedance of 50 , which can be installed in a coaxial line of a cryostat. The bath temperature of the noise s…
On-chip magnetic cooling of a nanoelectronic device
D. I. Bradley, A. M. Guénault, D. Gunnarsson +8
We demonstrate significant cooling of electrons in a nanostructure below 10 mK by demagnetisation of thin-film copper on a silicon chip. Our approach overcomes the typical bottlene…
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…
Nanoelectronic thermometers optimised for sub-10 millikelvin operation
J. R. Prance, D. I. Bradley, R. E. George +8
We report the cooling of electrons in nanoelectronic Coulomb blockade thermometers below 4 mK. Above 7 mK the devices are in good thermal contact with the environment, well isolate…
Primary thermometry in the intermediate Coulomb blockade regime
A. V. Feshchenko, M. Meschke, D. Gunnarsson +4
We investigate Coulomb blockade thermometers (CBT) in an intermediate temperature regime, where measurements with enhanced accuracy are possible due to the increased magnitude of t…
Setup for shot noise measurements in carbon nanotubes
Fan Wu, Leif Roschier, Taku Tsuneta +3
We have constructed a noise measurement setup for high impedance carbon nanotube samples. Our setup, working in the frequency range of 600 - 900 MHz, takes advantage of the fact th…
