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…
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…
Measuring the quantum states of a mesoscopic SQUID using a small Josephson junction
René Lindell, Jari Penttilä, Mika Sillanpää +1
We have experimentally studied the energy levels of a mesoscopic SQUID using inelastic Cooper-pair tunneling. The tunneling in a small Josephson junction depends strongly on its el…
Effect of quantum noise on Coulomb blockade in normal tunnel junctions at high voltages
J. S. Penttila, U. Parts, P. J. Hakonen +2
We have investigated asymptotic behavior of normal tunnel junctions at voltages where even the best ohmic environments start to look like RC transmission lines. In the experiments,…
"Superconductor-Insulator transition" in a single Josephson junction
J. S. Penttila, U. Parts, P. J. Hakonen +2
VI-curves of resistively shunted single Josephson junctions with different capacitances and tunneling resistances are found to display a crossover between two types of VI-curves: o…
