摘要：

We have investigated the interplay between Josephson coupling and quasiparticle interference effects in the resistance of a two-dimensional electron gas connected to superconducting electrodes with an interrupted ring geometry. By reducing the influence of the Josephson coupling strength at high dc current bias and large interelectrode spacing, we observed magneto-oscillations in the resistance with a period h2e, which we attribute to quasiparticle interference. © 1995 The American Physical Society.
