Query: High quality superconducting tunnel junction barriers using atomic layer
  deposition   We demonstrate a technique for creating high quality, large area tunnel
junction barriers for normal-insulating- superconducting or
superconducting-insulating-superconducting tunnel junctions. We use atomic
layer depo- sition and an aluminum wetting layer to form a nanometer scale
insulating barrier on gold films. Electronic transport measurements confirm
that single-particle electron tunneling is the dominant transport mechanism,
and the measured current-voltage curves demonstrate the viability of using
these devices as self-calibrated, low temperature thermometers with a wide
range of tunable parameters. The potential for fabricating high performance
junction refrigerators is also highlighted.
