From 1987 to 1989, he was a visiting scientist at the IBM Thomas J. Watson Research Center in Yorktown Heights, NY. From 1989 to 1996, he was a Research Staff Member at the IBM Zurich Research Laboratory, where he was manager of the New Materials and Heterostructures research group. From 1996 to 2011, he was a chaired professor at the Center for Electronic Correlations and Magnetism at the University of Augsburg, Germany.
Prizes and awards
The 2014 European Physical Society Condensed Matter Division Europhysics Prize is awarded to Jochen Mannhart. He was the 2008 recipient of the Gottfried Wilhelm Leibniz Prize of the Deutsche Forschungsgemeinschaft (German Research Society, DFG), award endowment 2.5 million euros, for his research in the field of experimental solid-state physics. In 1986, he received the Friedrich Förster Prize of the University of Tübingen, Germany.
Mannhart’s research includes the fabrication of novel all-oxide field-effect transistors, in which phase changes can be switched at interface layers, including phase changes to superconductivity. Under his leadership, his research group has developed an improved scanning probe microscope (frequency-modulated lateral force microscopy), which features a resolution of 77 picometers. With this instrument, his group succeeded in imaging individual atoms with subatomic resolution, which was used, for example, to investigate the atomic mechanism of friction. With P. Chaudhari and D. Dimos, J. Mannhart revealed that grain alignment is key to the fabrication of high-temperature superconductors with useful critical currents, so that they are suitable for practical applications such as modern high-Tc superconducting cables. Another research area is thermoelectronic generators.
