Hybrid single-electron turnstiles with thick superconducting electrodes for improved quasiparticle relaxation
J. T. Peltonen, A. Moisio, V. F. Maisi +3
We demonstrate shadow evaporation-based fabrication of high-quality ultrasmall normal metal -- insulator -- superconductor tunnel junctions where the thickness of the superconducti…
Thermal Conductance of a Single-Electron Transistor
B. Dutta, J. T. Peltonen, D. S. Antonenko +7
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.…
A cascade electronic refrigerator using superconducting tunnel junctions
H. Q. Nguyen, J. T. Peltonen, M. Meschke +1
Micro-refrigerators that operate in the sub-kelvin regime are a key device in quantum technology. A well-studied candidate, an electronic cooler using Normal metal - Insulator - Su…
Quasiparticle trapping in Meissner and vortex states of mesoscopic superconductors
M. Taupin, I. M. Khaymovich, M. Meschke +2
Nowadays superconductors serve in numerous applications, from high-field magnets to ultra-sensitive detectors of radiation. Mesoscopic superconducting devices, i.e. those with nano…
Tunnel-Junction Thermometry Down to Millikelvin Temperatures
A. V. Feshchenko, L. Casparis, I. M. Khaymovich +6
We present a simple on-chip electronic thermometer with the potential to operate down to 1 mK. It is based on transport through a single normal-metal - superconductor tunnel juncti…
A robust platform cooled by superconducting electronic refrigerators
Hung Q. Nguyen, Matthias Meschke, Jukka P. Pekola
A biased tunnel junction between a superconductor and a normal metal can cool the latter electrode. Based on a recently developed cooler with high power and superior performance, w…
