Abstract
We summarize recent experimental results on transport of diffusive and ballistic InAs-based (2-dimensional electron gas) submicron sized conductors connected to superconducting niobium contacts. Both ensemble-averaged and sample-specific transport is shown to depend on the difference in the superconducting phases tuned by a magnetic field. The ballistic case can be understood using a simple model based on phase-conjugated trajectories.
