Magnetoresistance of proximity coupled Au wires
D. A. Dikin, M. J. Black, V. Chandrasekhar
We report measurements of the magnetoresistance (MR) of narrow Au wires coupled to a superconducting Al contact on one end, and a normal Au contact on the other. The MR at low magn…

Influence of temperature dependent inelastic scattering on the superconducting proximity effect
M. J. Black, V. Chandrasekhar
We have measured the differential resistance of mesoscopic gold wires of different lengths connected to an aluminum superconductor as a function of temperature and voltage. Our exp…

Evidence for Supercurrent Quantization in Interfacial Josephson Junctions
M. J. Black, B. W. Alphenaar, H. Ahmed
We observe a series of discontinuities in the above gap current/voltage characteristics of highly transmissive Nb/Si superconductor/semiconductor interfaces. The bias at which each…
