NaI Aqueous Solution Surface Probed by Photoemission
نویسندگان
چکیده
For a NaI aqueous solution negative surface excess is inferred from the evolution of the ion photoemission signal as a function of the salt concentration. The experiments were performed using a 6μm diameter liquid microjet providing a free vacuum surface, which allows water molecules to evaporate without collisions, and hence enables the direct detection of photoelectrons originating from the liquid. Photons, 90 to 110 eV, were obtained from the MBI undulator beamline (U125-SGM).

Angle-resolved photoemission spectroscopy of liquid water at 29.5 eV
Angle-resolved photoemission spectroscopy of liquid water was performed using extreme ultraviolet radiation at 29.5 eV and a time-of-flight photoelectron spectrometer. SiC/Mg coated mirrors were employed to select the single-order 19th harmonic from laser high harmonics, which provided a constant photon flux for different laser polarizations. The instrument was tested by measuring photoemission...

متن کاملFermi surface and electronic structure of Pb/Ge„111..
The electronic structure of Pb/Ge~111! has been probed along the temperature-induced phase transition a 2A33A3R30°⇒333 using angle-resolved photoemission. The a2A33A3R30° phase is metallic due to the existence of a half-filled, dispersing surface band. The 333 phase is characterized by the appearance of an additional surface band with 333 periodicity, whose role in the phase transition is discu...
متن کاملPhotoemission measurements of Ultrathin SiO2 film at low take-off angles
The surface and interfacial analysis of silicon oxide film on silicon substrate is particularly crucial in the nano-electronic devices. For this purpose, series of experiments have been demonstrated to grow oxide film on Si (111) substrate. Then these films have been used to study the structure of the film by using X-ray photo emission spectroscopy (XPS) technique. The obtained results indicate...
متن کاملTime- and angle-resolved photoemission spectroscopy of hydrated electrons near a liquid water surface.
We present time- and angle-resolved photoemission spectroscopy of trapped electrons near liquid surfaces. Photoemission from the ground state of a hydrated electron at 260 nm is found to be isotropic, while anisotropic photoemission is observed for the excited states of 1,4-diazabicyclo[2,2,2]octane and I- in aqueous solutions. Our results indicate that surface and subsurface species create hyd...
