Electrical-transport properties of mesoscopic junctions consisting of a ballistic two-dimensional electron gas coupled at two sides to overlaying superconducting contacts are presented, The properties suggest that, despite the presence of transport limitin ...
We present experimental transport characteristics of long and ballistic superconductor - 2-dimensional electron gas - superconductor junctions obtained in a temperature range from 1K down to 10mK. Surprisingly the critical current I-c can be fitted to the ...
We report on the ab-plane optical reflectance of an iodine-intercalated Bi1.9Pb0.1Sr2CaCu2O8+delta single crystal in the 80-40000 cm(-1) (10 meV-5 eV) frequency range and at temperatures between 10 and 300 K. As compared to the iodine-free Bi2Sr2CaCu2O8+de ...
We have designed a diffusion-engineered, singlephoton spectrometer in the optical-UV range using a superconducting tunnel junction. The optical photon is absorbed in a Ta film and creates excess quasiparticles. These trap into an Al tunnel junction. Intern ...
We report on angle-resolved photoemission and superconductor-insulator-superconductor tunneling measurements of the normal and superconducting states of Bi2Sr2CaCu2O8+x single crystal samples and Bi2Sr2CaCu2O8+x - native oxide- lead (S-I-S) tunnel junction ...
We report measurements made on hybrid arrays consisting of superconducting wires along one direction of a square geometry and Josephson junctions along the perpendicular direction. The differential resistance Rd across the array as a function of normalized ...
We have fabricated YBa/sub 2/Cu/sub 3/O/sub 7/ ramp-type junctions incorporating a barrier layer of NdGaO/sub 3/ with a nominal thickness of 2 nm. The junctions exhibit pronounced Josephson effects and operate up to 82 K. The characteristics are well descr ...
