Parallel pumping of electrons
V. F. Maisi, Yu. A. Pashkin, S. Kafanov +2
We present simultaneous operation of ten single-electron turnstiles leading to one order of magnitude increase in current level up to 100 pA. Our analysis of device uniformity and…
Periodicity in Al/Ti superconducting single electron transistors
Sarah J. MacLeod, Sergey Kafanov, Jukka P. Pekola
We present experiments on single Cooper-pair transistors made of two different superconducting materials. We chose Ti and Al to create an energy gap profile such that the island ha…
Electronic Radio-Frequency Refrigerator
S. Kafanov, A. Kemppinen, Yu. A. Pashkin +3
We demonstrate experimentally that a hybrid single-electron transistor with superconducting leads and a normal-metal island can be refrigerated by an alternating voltage applied to…
Experimental investigation of hybrid single-electron turnstiles with high charging energy
A. Kemppinen, S. Kafanov, Yu. A. Pashkin +3
We present an experimental study of hybrid turnstiles with high charging energies in comparison to the superconducting gap. The device is modeled with the sequential tunneling appr…
