  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.
