The electrodynamic response of Nb in the frequency range above and below the energy gap 2\ensuremath{\Delta} is studied in the normal and in the superconducting state. A coherent source interferometer is utilized in the spectral range between 5 and $

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

Critical current and resistance of a single grain boundary in bulk bicrystals of the oxide superconductor BaPb1−xBix03 show a reentrant behavior in the temperature region below critical temperature of single crystal blocks. We established that the

Surface chemical modification is used to eliminate the problem of high surface recombination velocity and control surface band bending on InAs(100). Alkanethiols, RSH; R=CH3(CH2)n, both neat and in ethanolic solutions, are used to passivate this surf

Critical current and electrical transport properties of single grain boundaries in bulk bicrystals of the copperless oxide superconductors BaPb/sub 1-x/Bi/sub x/O/sub 3/ and Ba/sub 1-x/K/sub x/BiO/sub 3/ were measured in order to investigate quasipar

High-quality thin Nb and NbN films (60-100 A) are grown on (100) n + -InAs (n = 10 1 9 cm - 3 ) substrates by dc-magnetron sputter deposition. Studies of the electronic properties of interfaces between the superconductor and the semiconductor are don
We present a quantitative comparison of the magnetization measured by spin-polarized neutron reflectivity (SPNR) and DC magnetometry on a 1370 \AA\ -thick Nb superconducting film. As a function of magnetic field applied in the film plane, SPNR exhibi

The authors present the first detection of a superconducting proximity effect by optical techniques. Raman scattering on n{sup +}-InAs is performed through very thin, high-quality, superconducting Nb films grown directly on the (100) InAs surface. Th

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
