Steven W. Robey (Fed)

Physicist

Steve Robey's research interests are focused on the electronic structure of materials, particularly on physics at surfaces and interfaces and the electron dynamics and charge transfer processes that occur there. The primary research techniques employed are one- and two- photon photoemission measurements including non-linear photoemission processes and time-resolved pump-probe variations to study surface/interface electron dynamics. Current areas of interest are the interfacial electronic structure and dynamics that control charge separation processes that impact the development of renewable energy technologies, such as next generation photovoltaics and solar hydrogen production, and the electronic structure of emergent quantum materials.
