Driessen, E.F.C. Klapwijk, T.M. Berggren, K.K. Clem, J.R. Faculty Applied Sciences Department QN/Quantum Nanoscience Date 2012-05-03 Abstract We demonstrate experimentally that the critical current in superconducting NbTiN wires is dependent on their geometrical shape, due to current-crowding effects. Geometric patterns such as 90? corners and sudden expansions of wire width are shown to result in the reduction of critical currents. The results are relevant for single-photon detectors as well as parametric amplifiers.
