Tunable Josephson Junction ratchet
R. Menditto, H. Sickinger, M. Weides +4
We demonstrate experimentally the operation of a deterministic Josephson ratchet with tunable asymmetry. The ratchet is based on a Josephson junction with a ferromagnetic barri…
Model -- curves and figures of merit of underdamped deterministic Josephson ratchets
E. Goldobin, R. Menditto, D. Koelle +1
We propose simple models for the current-voltage characteristics of typical Josephson ratchets. We consider the case of a ratchet working against a constant applied counter force a…
Characterization of Anomalous Pair Currents in Josephson Junction Networks
I. Ottaviani, M. Lucci, R. Menditto +8
Measurements performed on superconductive networks shaped in the form of planar graphs display anomalously large currents when specific branches are biased. The temperature depende…
Hug-like island growth of Ge on strained vicinal Si(111) surfaces
L. Persichetti, R. Menditto, A. Sgarlata +2
We examine the structure and the evolution of Ge islands epitaxially grown on vicinal Si(111) surfaces by scanning tunneling microscopy. Contrary to what is observed on the singula…
