We have developed state-of-the-art synchrotron based extended x-ray absorption fine structure (EXAFS) measurements to enable the development and optimization of materials for electronics, photonics, energy conversion, sustainable energy, catalysis, and sensing applications. Materials that can be investigated include monolayers to bulk materials of all classes. Examples of ongoing measurement studies include (1) the bonding chemistry and local atomic structure of ferroelectric perovskites, (2) strain dependent electronic phase transitions, (3) chemistry and bonding at semiconductor oxide interfaces, (4) dopant activation, (5) high-k gate dielectrics, and (6) phase change materials. Such measurement studies offer the opportunity to develop and utilize world class x-ray instrumentation and detectors. Opportunities exist for the application of EXAFS to other advanced materials, including nanomaterials, for myriad applications.
