Yates, S. J. C., Baryshev, A. M., Baselmans, J. J. A., Klein, B., Güsten, R.

Microwave Kinetic Inductance Detectors (MKIDs) have great potential for large very sensitive detector arrays for use in, for example, sub-mm imaging. Being intrinsically readout in the frequency...

Enhancement of quasiparticle recombination in Ta and Al superconductors by implantation of magnetic and nonmagnetic atoms (2008)

Barends, R., Van Vliet, S., Baselmans, J. J. A., Yates, S. J. C., Gao, J. R., Klapwijk, T. M.

The quasiparticle recombination time in superconducting films, consisting of the standard electron-phonon interaction and a yet to be identified low temperature process, is studied for different...

Direct demonstration of circulating currents in a controllable $\pi$-SQUID generated by a 0 to $\pi$ transition of the weak links (2002)

Baselmans, J. J. A., Van Wees, B. J., Klapwijk, T. M.

A controllable $\pi$-SQUID is a DC SQUID with two controllable $\pi$-junctions as weak links. A controllable $\pi$-junction consists of a superconducting - normal metal - superconducting Josephson...

The controllable pi - SQUID (2001)

Baselmans, J. J. A., Van Wees, B. J., Klapwijk, T. M.

We have fabricated and studied a new kind of DC SQUID in which the magnitude and sign of the critical current of the individual Josephson junctions can be controlled by additional voltage probes...

Probing the electron-electron interaction in a diffusive gold wire using a controllable Josephson junction (1999)

Baselmans, J. J. A., Van Wees, B. J., Klapwijk, T. M.

We have studied the critical current of a diffusive superconductor - normal metal - superconductor (SNS) Josephson junction as a function of the electron energy distribution in the normal region....
