Ernst Bauer's Biography, Publications and Projects


Ernst G. Bauer received his MS (1953) and PhD (1955), both in physics, from Munich University, Germany. In 1958 he moved to the Michelson Laboratory in China Lake, California, where he became Head of the Crystal Physics Branch and U.S. citizen. In 1969 he accepted the position of Professor and Director of the Physics Institute at the Technical University Clausthal in Germany. In 1991 he was appointed Distinguished Research Professor at the Arizona State University, where he performed research on a part-time basis until 1996 in addition to his full-time duty in Germany. Since 1996 he is full-time at the Arizona State University. Since 2010 he is Distinguished Research Professor Emeritus still working full-time in ASU.

His interests have been in surface science and thin films. In 1958 he derived the classification of the thin film growth mechanisms, which he called Volmer-Weber, Stranski-Krastanov and Frank-van der Merwe mechanisms. This provided the theoretical thermodynamic framework of epitaxy which is used worldwide to this day. to understand epitaxy worldwide to this day. In 1962 he invented LEEM (Low Energy Electron Microscopy), which came to fruition in 1985. LEEM is a unique surface imaging method. The most important advantage of this technique is its ability to observe surface structure and dynamic processes in real space and real time at sample temperatures up to 1500 K. In the late eighties/early nineties he extended the LEEM technique in two important directions by developing two new surface microscopy methods: Spin-Polarized Low Energy Electron Microscopy (SPLEEM) and Spectroscopic Photo Emission and Low Energy Electron Microscopy (SPELEEM). The combination of these methods now allows a comprehensive (structural, chemical, magnetic, electronic) characterization of surfaces and thin films on the 10 nm scale.

Ernst Bauer's interest in the development of synchrotron radiation microscopy techniques and his involvement with the Synchrotron source Elettra in Trieste, Italy resulted in the development of the Nanospectroscopy beamline, which is today one of the leading synchrotron radiation microscopy facilities worldwide.

His work directly or indirectly impacts many areas of modern materials science: surfaces, thin films, electronic materials, and instrumentation. The invention and development of surface microscopy with slow electrons has revolutionized the study of surface science and thin film science.

Numerous LEEM instruments are now installed and are operating in many laboratories and synchrotron radiation facilities around the world (USA, Europe, Asia and Australia). An important recognition for Ernst Bauer's efforts in the field of surface microscopy is the increasing number of the scientists involved in LEEM research, which is reflected in the organization of bi-annual LEEM/PEEM workshops, the first of which was organized by Ernst Bauer and Anastassia Pavlovska in Arizona in 1998, followed by a second one in 2000 in Paris, a third one in New Mexico in 2002, the fourth in Holland in 2004, the fifth in Japan in 2006, the sixth in Italy in 2008, the seventh in New York, the eight in Hong Kong. The next number 9 conference will be held in Berlin in September 2014. Ernst Bauer built up the reputation of Arizona State University as a center of surface electron microscopy, thus broadening its international reputation in electron microscopy in general.

Ernst Bauer authored or co-authored 457 publications (among them 85 review papers and book chapters) and two books: "Electron Diffraction: Theory, Practice and Applications", 1958 (in German) and "Surface Microscopy with Low Energy Electrons", 2014. His papers are widely cited. (more than 12000 citations).

He has been for many years in the Advisory Board of Surface Science and is currently on the Editorial Board of physica status solidi (a). He served on the International Advisory Committee for a Grant-in-Aid Project of the Ministry of Education and Science in Japan and is presently a member of the Scientific Advisory Committee of the Advanced Light Source (ALS Berkeley, California). He is also a member of the International Advisory Boards of several periodic conferences. He was a visiting professor at the IME in Rio de Janeiro, at the University of Pretoria (South Africa), the University of Wisconsin-Milwaukee, Arizona State University, Synchrotron Radiation Source in Trieste, Italy and had longstanding scientific cooperation with NASA, Poland, Ukraine, Bulgaria, and Czech Republic. About 80 scientists had a possibility to perform high quality research in his group in Germany (53 of them from the European socialistic countries). Presently he has collaborations with Japan, Poland, Italy, Germany and Hong Kong.

The scientific achievements of Ernst Bauer have been multiply honored. He was the recipient of the E.W. Muller Award in 1985, the Gaede Prize of the German Vacuum Society in 1988, the Medard W. Welch Award of the American Vacuum Society in 1992, the Niedersachsenpreis for Science (Germany) in 1994, the BESSY Innovation Award on Synchrotron Radiation in 2004 and the very prestigious Davisson-Germer Prize of the American Physical Society in 2005. In 2003 Ernst Bauer received the first Award of the Japan Society of Promotion of Science's 141st Committee on Microbeam Analysis and was made an honorary member of this organization. He was elected a Member of the Göttingen Academy of Sciences in 1989, Fellow of the American Physical Society in 1991 and Fellow of the American Vacuum Society in 1994. In 2008 he was honored by a Humboldt Research Prize and Doctor Honoris Causa at the Marie Sklodovska-Curie University, Lublin, Poland. In 2012 he was appointed Fellow of Elettra Sincrotrone Trieste and in 2014 he received the Doctor Honoris Causa title from the University of Wroclaw, Poland. In 2015 he was elected as an International Fellow of the Japanese Society of Applied PhysicsPhysics and as Honorary Professor of the Chongqing University, China.
