Thomas Jung heads the Molecular Nanoscience group at the Laboratary for Micro- and Nanotechnology of PSI and the Nanolab of the University of Basel since since 2002. In 2009, he was promoted Honorary Professor and faculty member at the Faculty of Natural Sciences of the University of Basel. ( https://www.physik.unibas.ch/people/prof-jung.html )

He has contributed to about 150 scientific articles with an average number of almost 40 citations. These scientific accomplishments were covered ~60 times by the general press (e.g. NZZ, Basler Zeitung, Aargauer Zeitung, 20-minuten, New Scientist), by ~20 feature pages in newspapers and journals and radio; tv-broadcasts. From 1999 to 2002 he held the Presidency of the Swiss Physical Society. He held a visitor's position at the National Institute of Materials Science in Tsukuba, Japan, i.e. in their Materials Nano Architectonics program; he had been invited Scientist at the University of Wisconsin, Madison (with F. J. Himpsel) and Invited Professor at University of Kyoto (with K. Matsushige). Also, He was, for more than 10 years serving as a scientific committee member for the European Commission, is advisory board member for scientific journals and he organized and co-organized several conferences and workshops to promote scientific issues as well as the public understanding of science and technology.

Thomas Jung obtained a Diploma in Solid State Physics and Biophysics from ETH Zürich in 1987 after Thesis work on Photoemission (with H.C. Siegmann) and a Ph. D. in Solid State Physics and Surface Physics from the University of Basel in 1992. In his Ph. D. he developed dedicated Atomic Force Microscopy experiments for nanomechanics, magnetic imaging and for single flux line investigations above superconductors (supervised by H. J. Guentherodt). He implemented AFM at PSI's Zürich Research Laboratory (formerly RCA, later CSEM) before joining IBM's T. J. Watson Research Laboratory in Yorktown Heights NY (US) as a Post Doctoral Fellow in 1992. Here he worked on the electronic states of metallic wires and islands. (with Ph. Avouris and F. J. Himpsel) Between 1994 and 1997 he experimented with individual molecules, their self-assembly, positioning and their conformation at IBM's Zürich Research Laboratory in Rüschlikon, Switzerland (with J. K. Gimzewski).

1. Seminal reports on unexpected or new magnetic interactions between magnetic molecules and magnetic substrates. This activity includes the discovery of 2D ferrimagnetism in a binary molecular checkerboard assembly on Au(111). The system exhibits remanence at low (~3K) temperatures and is attributed to a complex and unique balance of Kondo and RKKY interactions.

3. Atom by atom condensation experiments performed in quantum boxes provided by a porous coordination network. A very distinct filling pattern reveals the complexity of the site-specific condensation influenced by the network, the substrate and the electronic state in the pore. Using these quantum box arrays, VdW forces between pairs of noble gas atoms i.e. Xe-Xe, Xe-Ne and Xe Kr have been measured.

The Molecular Nanoscience group is building and operating addressable nanostructures geared towards future spin-, quantum- and electron-based applications in devices and for specifically functional surfaces and materials.

The properties of the atomically precise supramolecular structures are explored by local and non-local physico-chemical experiments (i.e. by local probes and X-ray photo-absorption and photo-electron spectroscopy, also at advanced Synchrotron Light Sources) to explore their site specific local vs their cooperatively interacting behaviour. With his training in Physics and his specialization in Biophysics and Surface/Interface Science, Thomas has continuously been active in Applied Science. This led to ground breaking innovations for current or future products in collaboration with e.g. Roche, Sony, ABB, HighTec, Ferrovac, Straumann, Nanonis-SPECS.

Thomas’ group is also running the unique facility of the Photo Emission and Atomic Research Laboratory (PEARL) at PSI ( https://www.psi.ch/en/sls/pearl ) as well as they are responsible for the  the Atomic Force Microscopy Userlab of PSI ( https://www.psi.ch/en/lmn/scanning-probe-microscopy ). The high resolution Scanning Probe Microscopy and –Spectroscopy work is also performed in the Nanolab ( http://nanolab.unibas.ch/ ) of the Swiss Nanoscience Institute and the University of Basel.
