Attosecond electron dynamics in metallic nanoparticles, metallic surfaces, and nanoparticles-covered metallic surfaces
Abstract
In this project, we propose to implement a novel experimental approach to observe, in real-time, electron dynamics in solid-state systems relevant to the mission of the US Air Force. So far, time-resolved studies at the attosecond time scale have been restricted to a few benchmark atomic and molecular systems, due to the reduced complexity of their electron configuration, relative to complex systems, for example. In this project, we propose to merge the forefront expertise and state-of-the-art techniques of distinct scientific fields, namely laser physics and surface science, to explore the electron dynamics in metallic nanoparticles, metallic surfaces, and nanoparticles-covered metallic surfaces at the attosecond time scale. We aim to combine state-of-the-art attosecond sources, advanced surface science techniques, and sophisticated particle imaging techniques to investigate in a comprehensive study the fundamental dynamical mechanisms underlying surface chemical reactivity and catalysis. The measurements carried out in this project will foster the development of new theoretical models that are essential for designing more efficient catalysts and future materials. Finally, we expect that this new capability will offer promising possibilities to enhance our fundamental understanding of electron dynamics in solid-state system, and ultimately to identify ways to control them, which will pave the way toward the development of innovative technological devices.
