Education and career

Ibach received his doctorate in 1969 from

RWTH Aachen University RWTH Aachen University (), also known as North Rhine-Westphalia Technical University of Aachen, Rhine-Westphalia Technical University of Aachen, Technical University of Aachen, University of Aachen, or ''Rheinisch-Westfälische Technische Hoch ...

with his dissertation ''Thermische Ausdehnung von Silizium und Zinkoxid'' (Thermal expansion of silicon and zinc oxide) and habilitated there in 1972 with his habilitation thesis: ''Low energy electron spectroscopy — a tool for studies of surface vibrations''. From 1975 he was a docent and then a professor ordinarius at RWTH Aachen University, as well as director of the ''Institut für Schichten und Grenzflächen'' (Institute for Layers and Interfaces), and chair for Experimental Physics IV A in

Jülich Jülich (; in old spellings also known as ''Guelich'' or ''Gülich'', nl, Gulik, french: Juliers, Ripuarian: ''Jöllesch'') is a town in the district of Düren, in the federal state of North Rhine-Westphalia, Germany. As a border region betwe ...

. Since 2017 he is a visiting scientist at the '' Peter Grünberg Institut'' of the '' Forschungszentrum Jülich''. He is concerned with surface physics of solids and spectroscopic methods for this, electron energy loss spectroscopy, thin layers, adsorption and reaction of gases on surfaces, vibration spectroscopy on surfaces. He is the co-author, with , of a German standard textbook on solid state physics. He also wrote, with Douglas L. Mills, a standard reference on electron energy loss spectroscopy. In 1992 Ibach received the

Europhysics Prize The EPS CMD Europhysics Prize is awarded (currently every 2nd year) since 1975 by the Condensed Matter Division of the European Physical Society, in recognition of recent work (completed in the 5 years preceding the attribution of the award) by one ...

and in 1986 the

Medard W. Welch Award The Medard W. Welch Award is given to scientists who demonstrated outstanding research in the fields pertinent to the focus areas of the American Vacuum Society, which are "the basic science, technology development, and commercialization of materia ...
