摘要：

The effect of quasiparticle interferences on the transport between a two-dimensional electron gas in an InxGa1-xAs/InP heterostructure and the superconducting Nb electrodes of a Josephson junction is studied. The phase difference between the superconducting electrodes leading to the interference effects is adjusted by the Josephson effect. The quasiparticle interference results in a conductance plateau with a maximum at zero bias current through the Josephson junction. By applying a magnetic field the interference effect can be controlled.
