Fabrication of Nb-based superconducting single electron transistor
Description
We have fabricated Nb/(Al-)AlOx/Nb junctions with a single electron transistor (SET) geometry using conventional e-beam lithographic technique. It was possible to reach a clearly defined superconducting gap of 0.75 meV as measured in the current vs. voltage (I-V) characteristic curve, which corresponds to Tc of 4.6 K. The Josephson coupling energy was comparable to the charging energy, EJ∼Ec=30-40 μeV
