Femtochemistry at metal surfaces: Nonadiabatic reaction dynamics

Article Abstract:

Surface femochemistry on metal surfaces is based on electronically nonadiabatic coupling between a femosecond-laser-excited distribution of electron-hole pairs in the substrate and adsorbate vibrational degree of freedom. The resulting vibrational excitation eventually leads to chemical processes such as desorption, diffusion, or reactions between coadsorbed species and such a reaction can be described by direct frictional coupling to an ultrafast electronic transient.

Electronic excitations in metals and at metal surfaces

Article Abstract:

Electronic excitations have a profound impact on molecular motion induced by femtosecond laser pulses and play a large role in catalytic reaction as well as in spin transport within bulk metals, across interfaces, and at surfaces. At metal surfaces, in addition to bulk electron states, new electron states arise and these new states can be classified as intrinsic surface states and image-potential states.

Solvated electron on metal oxide surfaces

Article Abstract:

Detailed information on solvated electrons is obtained from solution-phase, cluster, and surface studies. Because metal oxide surfaces are prevalent in environmentally and technologically important settings, the discovery of wet electrons in hydrous overlayers is crucial to elucidate many important interfacial phenomena that are driven by light or other forms of electronic excitation.
