Abstract:
We report on the fabrication and evaluation of nanoscale YBa2Cu3O7-x (YBCO) constrictions using focused-ion-beam techniques for potential application as YBCO bolometers. A gold protective layer was found to be critical for supressing contamination from gallium ions in order to obtain high critical current densities. Further processing using a radio-frequency plasma to remove the gold protective layer has also been studied and was found to be effective in minimizing sample damage resulting from overheating. Current-voltage measurement indicate that the nanobridges go through the transition from superconducting to normal state with different dissipation mechanism including flux creep and hot spot formation.

Beams
Based on geometry, beams can be straight, tapered, or curved. Straight beams are the most common type and have a constant cross-section throughout their length. Tapered beams, on the other hand, have a varying cross-section along...
