Real-time observation of discrete Andreev tunneling events
V. F. Maisi, O. -P. Saira, Yu. A. Pashkin +3
We provide a direct proof of two-electron Andreev transitions in a superconductor - normal metal tunnel junction by detecting them in a real-time electron counting experiment. Our…
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…
Photon assisted tunneling as an origin of the Dynes density of states
J. P. Pekola, V. F. Maisi, S. Kafanov +6
We show that the effect of a high-temperature environment in current transport through a normal metal-insulator-superconductor tunnel junction can be described by an effective dens…
