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…
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…
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…
