Temperature-dependent Raman spectroscopy is used to investigate the effect of superconductivity on the near-surface electronic structure of a semiconductor in good electrical contact with a superconductor. The light scattering is performed through a

Reproducible planar tunnel junctions based on high-quality YBa 2 Cu 3 O 7 thin films are studied as a junction of crystallographic orientation. Using Pb as a counter-electrode, all junctions exhibit zero bias anomalies, the sign of which depends upon

A systematic study of the conductance of Y1−xPrxBa2Cu3O7/Pb planar tunnel junctions as a function of Pr concentration, x, and crystallographic orientation is presented. For fixed Pr concentration, the tunneling conductance is the same when tunnelin

Raman scattering on InAs coated with 60 to 100A thick Nb films (Tc=2.5 to 5K) is studied. The Nb films, sputtered ontoin-situ ion-etched n+-InAs (1.2×1019cm−3) are flat to ∼5A. The low-frequency coupled plasmon-phonon Raman mode (L_) associated

Utilizing a thickness-spread technique, proximity-effect studies of Nb juxtaposed with rare-earth alloys and a heavy-fermion metal (CeCu6) have been undertaken. The 20 to 1000 A thick Nb films exhibit a bulk Tc down to a 130 A thickness and the mean
