✦ Synopsis

We report that the energy dissipation of Josephson junction can be controlled by quasi-particle injection. We fabricated two Josephson junctions on the narrow aluminum wire and controlled the energy dissipation of one junction by quasi-particle injection from the other. We observed the retrapping current increased as the quasi-particles were injected. We also studied the heating effect of our measurement.

Control of the critical current in a superconductor/two-dimensional electron gas Josephson junction by means of an injection current is reported. The control mechanism is explained by a theoretical model, which takes ballistic transport across the junction and diffusive transport through the semicon
