CU FEMM Director, Sadegh Yazdi 

Sadegh Yazdi is a Research Associate Professor at the Renewable and Sustainable Energy Institute (RASEI), and the Director of the Facility for Electron Microscopy of Materials (CU FEMM) at the University of Colorado. Before joining CU and RASEI, Sadegh was a research scientist at the Department of Materials Science and NanoEngineering (MSNE) at Rice University, in charge of an FEI Titan Themis, a double aberration-corrected scanning transmission electron microscope. Prior to his position at Rice, he was a Researcher and Postdoctoral Fellow at the Center for Electron Nanoscopy (CEN) in the Technical University of Denmark between 2012 and 2015. During this period, using advanced electron microscopy techniques, Sadegh studied semiconductor nanowires for solar cell and light emitting diode applications.

Sadegh earned his Ph.D. in 2012 from Imperial College London under the supervision of Prof. David McComb and Prof. Rafal Dunin-Borkowski. His Ph.D. was focused on the development of off-axis electron holography for studying semiconductor devices under working conditions in-situ in transmission electron microscopes. Sadegh obtained his M.Sc. from Sharif University of Technology (2004) and B.Sc. from Shahid Beheshti University (2002) in Iran in Electronics and Electrical Engineering.

Dr. Yazdi’s research interests include developing novel electron microscopy techniques for exploring the links between the underlying atomic arrangements of energy-related materials and their performance, properties, and synthesis. To characterize nanostructures at atomic levels, Sadegh uses advanced electron microscopy techniques such as aberration-corrected scanning transmission electron microscopy (AC-STEM), low-voltage and monochromated high-resolution transmission electron microscopy (HRTEM), off-axis electron holography (OAEH), monochromated electron energy loss spectroscopy (EELS), electron tomography (ET), and a wide range of in-situ electron microscopy techniques.
