Ion beam sputtering method for progressive reduction of nanostructures dimensions
M. Savolainen, V. Touboltsev, P. Koppinen +2
An ion beam based dry etching method has been developed for progressive reduction of dimensions of prefabricated nanostructures. The method has been successfully applied to aluminu…
Turnstile behaviour of the Cooper-pair pump
J. J. Toppari, J. M. Kivioja, J. P. Pekola +1
We have experimentally studied the behaviour of the so-called Cooper pair pump (CPP) with three Josephson junctions, in the limit of small Josephson coupling EJ < EC. These experim…
Experimental Investigation of Microwave Enhanced Cotunneling in SET Transistors
Martin Manscher, Marko T. Savolainen, Jesper Mygind
Cotunneling is an important error process in the application of single electron tunneling devices for metrological and electronic applications. Here we present an experimental inve…
Adiabatic transport of Cooper pairs in arrays of Josephson junctions
J. P. Pekola, J. J. Toppari, M. Aunola +2
We have developed a quantitative theory of Cooper pair pumping in gated one-dimensional arrays of Josephson junctions. The pumping accuracy is limited by quantum tunneling of Coope…
