Research Description

Professor Thiel's research is concerned with the development of new characterization tools and methodologies appropriate for nanotechnology. Very often, physical properties are limited by structural, chemical, and electronic inhomogeneities on the nanometer scale. As devices and processes become smaller, it therefore becomes more and more critical to understand and measure structure - property relationships on atomic dimensions. Accordingly, the major thrust of Thiel's research is in developing electron, ion, and photon based tools and techniques. Please visit the Thiel Research Group webpage for further information.
