Electron dynamics in a heterogeneous system: thin Ag films on Si(100)

Photochemistry on Thin Metal Films: Probe of Electron Dynamics in Metal-Semiconductor Heterosystems

“…Given that electrons with a wider distribution in parallel momenta will be able to attach to a molecular affinity level, the finer details of the electronic structure will not be visible in the photodesorption cross section. A forthcoming 2PPE study of the electron dynamics in Ag films on Si(100), as the ones used here, indicates that at 4.7 eV excitation the photoyield is dominated by electrons originating from the Si substrate and having traversed into the Ag film [24].…”
