The discovery of the photoelectric effect by Heinrich Hertz in 1887 set the foundation for over
125 years of hot carrier science and technology. In the early 1900s it played a critical role in …

Femtochemistry addresses fundamental processes of chemical reaction dynamics such as
bond formation and breaking, which occur typically on a femtosecond time scale (1 fs) 10-15 …

Heating of a ruthenium surface on which carbon monoxide and atomic oxygen are
coadsorbed leads exclusively to desorption of carbon monoxide. In contrast, excitation with …

Time-resolved two-photon photoemission (2PPE) at various photon energies is used to
investigate the relaxation dynamics of hot electrons in Cu (111), applying auto-and cross …

Theoretical aspects of dynamical processes at metal surfaces are reviewed. Experimental
challenges to theory are presented and progress toward meeting these challenges is …

We present the first demonstration of the use of ultrafast extreme-ultraviolet pulses to directly
monitor a surface chemical reaction on femtosecond time scales. By adsorbing molecular …

Photochemical surface processes are initiated by the absorption of photons by an adsorbate
or the substrate, and followed by various energy transfer and relaxation processes that lead …

Removal of low-concentration CO in the atmosphere and conversion of concentrated CO
into energy fuels with a low energy input are critically important for our sustainable …

Plasmonic photocatalysis enables innovation by harnessing photonic energy across a broad
swathe of the solar spectrum to drive chemical reactions. This review provides a …

Great success has been achieved in the modeling of gas-surface elementary processes by
the use of the Born-Oppenheimer approximation. However, in metal surfaces low energy …
