Surface and Interface Complexity

Abstract: Complexity in materials science and solid-state physics is often associated with multiple elements, structures, or phases coexisting in one material. A pure metallic single-crystal, on the other hand, constitutes the simplest expression of a solid: A large array of perfectly ordered atoms… until the surface is reached. In this seminar, I will present results from my research that showcase how even the simplest surfaces and interfaces present complex behavior. I will also show how complexity evolves when materials have coexisting elements, structures, and phases over dynamic out-of-equilibrium conditions. I will briefly cover systems ranging from 2D growth and alloying on ruthenium (0001) single crystal surfaces to surface-mediated chemical reactions in operating solid-oxide fuel-cells using Pt catalysts.   Some of the most challenging surfaces discussed in this seminar include complex metal-hydrides for chemical hydrogen storage and soot particle formation and growth inside flames.


Bio: Farid El Gabaly received a Ph.D. degree in Condensed Matter Physics from the University of Madrid (Spain) in 2006, and was a Postdoctoral Researcher at Lawrence Berkeley National Laboratory from 2006 to 2008. He then joined Sandia National Laboratories (Livermore, CA site) where he is currently a Principal Member of the Technical Staff in the Materials Physics department. Dr. El Gabaly holds one US/International patent and has authored over 45 articles in peer-reviewed journals, which have received over 1400 citations in the last 5 years.
