We have investigated hybrid superconductor/semiconductor structures consisting of modulation-doped InAs quantum wells contacted by closely spaced niobium electrodes, and showing induced superconductivity in the InAs. The resistance of these semiconductor-coupled weak links does not disappear abruptl

Current transport through InAs A1Sb quantum wells contacted with superconducting Nb electrodes shows strong evidence for the presence of multiple Andreev reflections (AR's). The efficiency of the multiple AR process is greatly enhanced by the specular normal reflection of electrons at the backplane

Amplitude of the Coulomb blockade oscillations is calculated for a single-mode Josephson junction with large electron transparency D. It is shown that the Coulomb blockade is suppressed as D + 1. The suppression is described quantitatively in terms of the Landau-Zener transition in imaginary time.

The dc Josephson effect in a superconducting quantum point contact, where supercurrent flows through a small number of channels, is reviewed. The central role of Andreev levels is emphasized which carry the whole supercurrent in short symmetric Josephson junctions including tunnel junctions. A simpl
