Biography
Oliver Ambacher received the Dipl.-Phys. degree from Ludwig-Maximilians, Munich, Germany, in 1989, and the Dr. degree (with hons.) from the Technical University (TU) Munich, Munich, in 1993.
In 1993, he joined the Walter Schottky Institute, TU-Munich. Since 1995, the research of his group is focused on fabrication of GaN-based devices such as UV detectors, surface acoustic wave devices, or microwave amplifiers, as well as on the understanding of polarization induced effects in group-III nitride heterostructures and quantum wells. During 1998–1999, he spent one year with Cornell University, Ithaca, NY, USA, as an Alexander von Humboldt Fellow. He became a Professor of nanotechnology and the Head of the Institute for Solid State Electronics, Technical University of Ilmenau, Ilmenau, Germany, in 2002. In 2004, he was elected as the Head of the new Center of Micro and Nanotechnologies. In 2007, he became the Head of the Fraunhofer Institute of Applied Solid State Physics, Freiburg, Germany, and a Professor of compound microsystems at Freiburg. Since 2017, he holds the Chair of Power Electronics, Institute for Sustainable System Engineering, University Freiburg, Breisgau, Germany.
