CsI thin film photocathodes of 600 nm thickness deposited on polished Al surfaces by resistive evaporation technique were studied by angle-resolved X-ray photoelectron spectroscopy (ARXPS), before and after UV-irradiation under vacuum. It is shown that the ...
We have determined the effective attenuation length of photoelectrons over the range of kinetic energies from 4 to 6 keV in Co, Cu, Ge, and Gd2O3. The intensity of the substrate (Si) and overlayer core level peaks was measured as a function of the thicknes ...
The adsorption of trimesic acid (TMA) on Cu(110) has been studied in the temperature range between 130 and 550 K and for coverages up to one monolayer. We combine scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), reflection absor ...
Titanium-containing amorphous hydrogenated carbon films (a-C:H/Ti) have been deposited by a medium-frequency-driven physical vapor deposition plasma-enhanced chemical-vapor deposition process at 40 kHz. Core-level photoelectron spectroscopy and valence-ban ...
Spectromicroscopy with the imaging technique of X-ray photoelectron emission microscopy (X-PEEM) is a microchemical analytical tool installed in many synchrotron radiation laboratories, and which is finding application in diverse fields of research. The me ...
The photoionization dynamics of aniline doped helium droplets has been investigated by photoelectron spectroscopy. The photoelectron spectra resemble closely that of gas phase aniline, except for a dropletsize- dependent shift. This shift is caused by lowe ...
We review some recent spectroscopic results on low-dimensional systems, including high-T-c superconductors, and charge density wave compounds. We briefly discuss the reasons for the present interest in these materials, and the relevance of band mapping exp ...
The development of narrow bandwidth tunable laser systems in the vacuum UV region of the electromagnetic spectrum and of new exptl. methods has recently enabled a significant improvement in the resoln. that can be achieved by photoelectron spectroscopy. Th ...
Using a first-principles approach, we investigate the effect of interdimer interactions on N Is core-level shifts at the NH3 saturated Si(100)-2 X 1 surface. Fully relaxed model structures are generated in which -NH2 groups on adjacent dimers in a row are ...
Recent high-resolution photoemission results on high-T-c superconductors and other low-dimensional systems solve some critical issues but also open new fundamental questions. A recent breakthrough enabled us to clarify the interplay of conflicting periodic ...
