Change in the sign of the Josephson interaction in a controlled SINIS Josephson junction
This letter analyzes an SINIS Josephson junction in which an auxiliary current flows through the N electrode. In the absence of a voltage across the S electrodes, there is therefore a voltage V across the N and S electrodes. A calculation of the Josephson current as a function of V shows that the critical current Ic decreases with increasing V and changes sign at V=0.7l Lie. Methods for experimentally observing a transition of an SINIS structure from an ordinary Josephson junction to a 77 junction are discussed. © 1995 American Institute of Physics.
