WebJun 8, 2007 · Abstract. We found monochromatic electron photoemission from large-area self-assembled monolayers of a functionalized diamondoid, [121]tetramantane-6-thiol. Photoelectron spectra of the diamondoid monolayers exhibited a peak at the low–kinetic energy threshold; up to 68% of all emitted electrons were emitted within this single energy …
When a photoemission event takes place, the following energy conservation rule holds: where is the photon energy, is the electron BE (binding energy with respect to the vacuum level) prior to ionization, and is the kinetic energy of the photoelectron. If reference is taken with respect to the Fermi level (as it is typically done in photoelectron spectroscopy) must be replaced by the sum of the binding energy (BE) relative to the Fermi level, , and the sample work function, . diabetic walking shoes size 13.5 ukWebOct 31, 2024 · From the photoemission spectrum, it was possible to observe three coexisting copper species.
