 Prof. Stöhr’s research has focused on the development of novel investigative techniques based on soft x-ray synchrotron radiation for exploring the structure, electronic and magnetic properties of surfaces and thin films.He played a major role in developing the surface extended x-ray absorption fine structure (SEXAFS) technique as a tool for exploring surface structures, especially atoms bonded to surfaces.He also developed the near edge x-ray absorption fine structure (NEXAFS) technique for the study of simple and complex molecules bonded to surfaces and for the study of thin polymer films.
