Electronic and Optical Properties of Thin-Film Superconductors and Superconductor -Semiconductor Interfaces
Application of an external ac field results in steps in the current-voltage characteristics at Vn = nho/2e. Experimental parameters of a highly-doped n+-InAs are used to obtain estimates for future experiments to be conducted to test the predictions of the model.

Electronic and optical properties of thin-film superconductors and superconductor - semiconductor interfaces
… studies of the interfaces between high-quality thin film Nb and NbN superconductors, and (100) n+-InAs (10^19cm^-3 ) are done by transport and optical measurements. For the first time, the proximity effect in superconductor-semiconductor interfaces is observed using Raman scattering. The InAs …

Growth and characterisation of thin film superconductors on oxides, silicon and silicides
High Tc thin film superconductors are of great interest because of their potential applications, particularly in the microelectronics field. A successful superconductor microelectronic technology depends both on the ability to grow good quality superconducting thin films, and the need to …

Optical properties of ultra-thin niobium nitride films for single photon detectors
… of the properties of reactively sputtered ultra-thin films of niobium nitride (NbN) and niobium titanium nitride (NbTiN). Using Variable Angle Spectral Ellipsometry (VASE), I found that the optical properties of NbN films appear to have a critical thickness above which the optical parameters …

Magnetic flux flow and fluctuation effects in thim film superconductors
Critical state measurements of single and binary thin film systems have been measured as a function of transport current density, magnetic field, temperature, and degree of annealing. Results are interpreted in terms of the present understanding of the mixed state in thin films. Studies of vorteK …
