A hybrid superconductor-normal metal electron trap as a photon detector
S. V. Lotkhov, A. B. Zorin
A single-electron trap built with two Superconductor (S) - Insulator (I) - Normal (N) metal tunnel junctions and coupled to a readout SINIS-type single-electron transistor A (SET A…
Long hold times in a two-junction electron trap
A. Kemppinen, S. V. Lotkhov, O. -P. Saira +3
The hold time of a single-electron trap is shown to increase significantly due to suppression of environmentally assisted tunneling events. Using two rf-tight radiation shields…
Towards the observation of phase locked Bloch oscillations in arrays of small Josephson junctions
Felix Maibaum, Sergey V. Lotkhov, A. B. Zorin
We have designed an experiment and performed extensive simulations and preliminary measurements to identify a set of realistic circuit parameters that should allow the observation…
Pumping properties of the hybrid single-electron transistor in dissipative environment
S. V. Lotkhov, A. Kemppinen, S. Kafanov +2
Pumping characteristics were studied of the hybrid normal-metal/superconductor single-electron transistor embedded in a high-ohmic environment. Two 3 micrometer-long microstrip res…
Single electron transistors with high quality superconducting niobium islands
R. Dolata, H. Scherer, A. B. Zorin +1
Deep submicron Al-AlOx-Nb tunnel junctions and single electron transistors with niobium islands were fabricated by electron beam gun shadow evaporation. Using stencil masks consist…
The single electron R-pump: first experiment
S. V. Lotkhov, S. A. Bogoslovsky, A. B. Zorin +1
We fabricated and tested the single electron R-pump, i.e. a three-junction Al circuit with on-chip Cr resistors. We show that due to the presence of the resistors (R > h/e^2 = 25.8…
