Abstract

An experimental search for the Bloch oscillations has been carried out with lead-alloy, and aluminum Josephson tunnel junctions of area S≈0.01μm², isolatated from their electromagnetic environment by high-ohmic metallic resistors. Under irradiation with microwave frequencies f=0.4 to 10 GHz, the dc differential resistance dV/dI, as a function of the dc current I, showed peaks at I=±2ef. Thiseffect arises due to the periodic electrical recharging of the junction by discrete Cooper pairs, and can be explained by the “orthodox” theory of Bloch oscillations.
