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.
In 2012 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.
