Energetic Deposition of Niobium Thin Film in Vacuum
Niobium thin films are expected to be free of solid inclusions commonly seen in solid niobium. For particle accelerators, niobium thin film has the potential to replace the solid niobium in the making of the accelerating structures. In order to understand and improve the superconducting performance …

Spectroscopic studies of high-temperature superconductors on planar tunnel junction devices and nanofabricated point contact junctions
… is atomic layer deposition (ALD) to grow ultra-thin and low-defect Al2O3 tunnel junction barriers, developed on sputter-deposited Nb thin films. The conductance characteristics at low temperature show the clear density of states signature of superconducting Nb. The junction resistance times area …

Mechanical relaxations, spin glasses and 1/f resistance noise
… measurements of the anelastic piezoresistance in thin films of bismuth, niobium and iron to demonstrate a connection between mechanical anelastic relaxations and electrical 1/f noise from the motion of defects. We have found that the connection between 1/f noise and mechanical relaxation is more …
