Prof. Klapwijk is a pioneer in the field of non-equilibrium
superconductivity and made important contributions to what is now
known as Blonder-Tinkham-Klapwijk theory. His
research was also dedicated to superconductor-semiconductor
systems. While at Groningen he worked closely with polymer chemists
studying opto-electronic properties
of semiconducting polymers using his insight in traditional semiconductors.
After moving to Delft he stimulated another activity originating
in his Groningen-research programme: to use
superconductors for astronomical instrumentation. He has made significant
contributions to the so-called hot-electron
bolometers as well as superconducting tunnel-junctions
for heterodyne-detection in the range from 300 GHz
to 5 THz. This research has found practical usage in the Herschel
Space telescope and the Atacama Large Millimeter Array through his
group?s collaboration with the Netherlands Institute of Space
research. He has pioneered the use of NbTiN for single-photon
detectors. More recently he has shifted his interest to so-called
superconducting resonators, or microwave kinetic inductance detectors,
which are suitable for multi-pixel arrays and which pose
very demanding questions to strongly disordered superconductors.
T. M. Klapwijk received the Kamerlingh Onnes prize for «long-term outstanding and pioneering contributions to the
experimental superconductivity research», in particular «for seminal
experiments on the superconducting properties of superconductor-ferromagnet
and superconductor-normal metal nano structures».
In 2013 he was appointed Knight in the Order of the Dutch
Lion for his pioneering and leading academic work.
