Abstract
Double-barrier Nb/AlOx/Al/AlOx/Nb devices were fabricated and investigated in direct-current and alternating-current (ac) electromagnetic fields. The occurrence of current singularities and of the ac Josephson effect at T = 4 .2 K are demonstrated. In a three-terminal configuration, a transistor-like behaviour of the structure is also observed.
