Josephson effect and tunneling spectroscopy in Nb/Al2O3/Al/MgB2 thin films junctions

G. Carapella, N. Martucciello, G. Costabile +3

We report the demonstration of dc and ac Josephson effects as well as tunneling spectroscopy measurements on Nb/Al2O3/Al/MgB2 thin films heterostructures. Data on dc Josephson effe…
