Jochen Mannhart
Jochen Mannhart (born April 24, 1960 in Metzingen ) is a German physicist .
Life
Mannhart studied physics at the University of Tübingen from 1980 to 1986 , where he received his doctorate in 1987 and his habilitation in 1994 .
From 1987 to 1989 he was visiting scientist at the IBM Thomas J. Watson Research Laboratory in Yorktown Heights (New York) and then until 1996 at the IBM Laboratorium Zürich , where he was manager of the group “New Materials and Heterostructures” from 1992 to 1996. In 1996 he received a call on the Chair of Experimental Physics VI, Center for Electronic Correlations and Magnetism at the University of Augsburg .
In the summer of 2011 he moved to the Max Planck Institute for Solid State Research in Stuttgart as a member of the board of directors .
Prizes and awards
In June 2014 Jochen Mannhart was awarded the CMD Europhysics Prize of the European Physical Society . On December 6, 2007 he was awarded the Gottfried Wilhelm Leibniz Prize by the German Research Foundation (DFG), endowed with 2.5 million euros, as the 2008 Prize Winner for his research in the field of experimental solid-state physics . In 1986 he received the Dr. Friedrich Förster Prize from the University of Tübingen. In 2005 he became a Fellow of the American Physical Society .
research
Mannhart developed a. a. new purely oxidic field effect transistors in which phase transitions are switched at interfaces, for example transitions to superconductivity. With his group he improved scanning probe microscopes (frequency modulated lateral force microscopy ), which for the first time also resolved subatomically at a resolution of 77 picometers , and with which his group u. a. studied the atomic mechanism of friction. Mannhart optimized the grain interfaces in high-temperature superconductors for their practical use, for example in cables (enlargement of the crystal surfaces, doping of the surfaces, alignment of the crystals).
