Single-charge escape processes through a hybrid turnstile in a dissipative environment
Sergey V Lotkhov, Olli-Pentti Saira, Jukka P Pekola +1
We have investigated the static, charge-trapping properties of a hybrid superconductor---normal metal electron turnstile embedded into a high-ohmic environment. The device includes…
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…
Environmentally Activated Tunneling Events in a Hybrid Single-Electron Box
O. -P. Saira, M. Mottonen, V. F. Maisi +1
We have measured individual tunneling events and Coulomb step shapes in single-electron boxes with opaque superconductor-normal metal tunnel junctions. We observe anomalous broaden…
Detection of mechanical resonance of a single-electron transistor by direct current
Yu. A. Pashkin, T. F. Li, J. P. Pekola +6
We have suspended an Al based single-electron transistor whose island can resonate freely between the source and drain leads forming the clamps. In addition to the regular side gat…
Violation of the fluctuation-dissipation theorem in time-dependent mesoscopic heat transport
Dmitri V. Averin, Jukka P. Pekola
We have analyzed the spectral density of fluctuations of the energy flux through a mesoscopic constriction between two equilibrium reservoirs. It is shown that at finite frequencie…
