Phonon-blocked junction refrigerators for cryogenic quantum devices
E. Mykkänen, J. S. Lehtinen, A. Ronzani +4
Refrigeration is an important enabler for quantum technology. The very low energy of the fundamental excitations typically utilized in quantum technology devices and systems requir…
Coulomb Blockade Thermometry on a Wide Temperature Range
O. M. Hahtela, A. Kemppinen, J. Lehtinen +11
The Coulomb Blockade Thermometer (CBT) is a primary thermometer for cryogenic temperatures, with demonstrated operation from below 1 mK up to 60 K. Its performance as a primary the…
Realisation of a quantum current standard at liquid helium temperature with sub-ppm reproducibility
Stephen Giblin, Emma Mykkänen, Antti Kemppinen +7
A silicon electron pump operating at the temperature of liquid helium has demonstrated repeatable operation with sub-ppm accuracy. The pump current, approximately 168 pA, is measur…
Superconducting MoSi nanowires
J. S. Lehtinen, A. Kemppinen, E. Mykkänen +2
We have fabricated disordered superconducting nanowires of molybdenium silicide. A molybdenium nanowire is first deposited on top of silicon, and the alloy is formed by rapid therm…
