Microwave irradiation of Nb-InAs-Nb single-junctions demonstrates that the half-integer Shapiro step is caused by ac nonequilibrium supercurrents. In addition, nonequilibrium dc supercurrents are observed as a conductance enhancement around zero bias. Both effects persist to temperatures integer Sha
~Istituto di Cibernetica del C.N.R., 1-80072, Arco Felice (NA), Italy We present three novel processes for the fabrication of two or more vertically stacked Josephson tunnel junctions all based on the Nb/Al -AlOx/Nb technology. The dynamical properties of stacks of up to five, high-quality and low
