Tungsten (W) is considered to be one of the most promising plasma-facing materials (PFMs)
for next-step fusion energy systems. However, as a PFM, W will be subjected to extremely …

This review introduces hydrogen depth profiling by nuclear reaction analysis (NRA) via the
resonant 1 H (15 N, αγ) 12 C reaction as a versatile method for the highly depth-resolved …

The surface electronic states of W (110)-(1× 1) H have been measured using spin-and angle-
resolved photoemission. We directly demonstrate that the surface bands are both split and …

The bonding energies of the Pd 3d and the C 1s core levels have been studied for the p (2√
2×√ 2) R45, p (3√ 2×√ 2) R45, and p (4√ 2×√ 2) R45 structures of CO on Pd (100) …

Two-dimensional Fermi contours of clean and hydrogen-induced surface electronic states
have been systematically measured vs coverage of H on W (110) using angle-resolved …

We present a quantitative study of the atomic structure of the clean and H-covered W (110)
surface employing an analysis of lowenergy electron diffraction (LEED) as well as density …

We have used density functional theory to investigate hydrogen adsorption and diffusion on
a W (110) surface. Hydrogen adsorption structures were examined from low coverage to one …

Two previously unappreciated features in photoemission spectra from alkali atoms adsorbed
on W (110), namely, the sign of the alkali-induced surface-atom core-level shift of the …

We have measured high-resolution 4 f 7 2 core-level photoemission spectra from W (110) in
the presence of submonolayer O coverages. Coverages≤ 0.5 monolayer (ML) were …

We report on density functional theory calculations that have been performed to
systematically investigate the hydrogen-surface interaction as a function of surface …
