Transport Studies on Single Superconductor/Two-Dimensional-Electron-Gas Interfaces,ke the S/2DEG/S junctions treated in the following chapters. First, we shall focus on the effect of different surface treatments prior to the deposition of the Nb electrodes. Measurements of the differential resistance as a function of the voltage drop at the interface give direct information about

Josephson Current in Superconductor/Two-Dimensional-Electron-Gas Junctions,phase coherence is crucial for the occurrence of a Josephson supercurrent. In the first part of this chapter, the theoretical concepts will be discussed, starting with the simplest model of an ideal one-dimensional junction, without any barriers at the SN interface and with no Fermi velocity mismatc

Nonequilibrium Josephson Current,preceding chapter, is to control the carrier concentration in the semiconductor with a gate electrode. A typical example of this kind of structure is the Josephson field effect transistor. In this chapter we shall discuss how a Josephson supercurrent can be controlled by injecting nonequilibrium car

Conclusion,een reviewed. A crucial parameter for all of these structures is the transparency of the superconductor/two-dimensional-electron-gas interface. Optimizing the transparency is of course mainly a technological challenge but, as was shown, a detailed understanding of the transport processes is necessar

Josephson Current in Superconductor/Two-Dimensional-Electron-Gas Junctions,ed, starting with the simplest model of an ideal one-dimensional junction, without any barriers at the SN interface and with no Fermi velocity mismatch. Later on, more elaborate models will be introduced, which describe the experimental situation more appropriately.

Carrier Transport Through a Superconductor/Normal-Conductor Interface,ductor interface. However, the experimental results obtained on single interfaces suggest that some extensions, e.g. the inclusion of the proximity effect, are necessary in order to obtain a better theoretical description of the experimental findings.

Gate-Controlled Superconductor/Two-Dimensional-Electron-Gas Junctions, related to the wave nature of the particles can also be addressed by studying superconductor/semiconductor structures controlled by a gate. Typical examples, which will be discussed below, are interference effects due to Fabry—Pérot resonances, fluctuation and localization effects, and the quantization of the critical current.
