Computer simulations allow for the investigation of many materials properties and processes
that are not easily accessible in the laboratory. This is particularly true in the Earth sciences …

ITER will use beryllium as a plasma-facing material in the main chamber, covering a total
surface area of about 620 m 2. Given the importance of beryllium erosion and co-deposition …

We investigated surface properties of metals by performing first-principles calculations. A
systematic database was established for the surface relaxation, surface energy (γ), and …

We present high-resolution photoemission experiments of the Γ-surface state of Be (0001).
The spectral function near the Fermi wave vector reveals a strong quasiparticle peak due to …

We use dynamical low-energy electron diffraction (LEED) to determine the surface structure
of α− Al 2 O 3 (0001). Sapphire surfaces are prepared in three different ways, and the …

Density functional theory and a plane-wave basis pseudopotential technique are applied to
calculate the bulk and the (0001) surface properties of hexagonal-close-packed (hcp) …

Dynamical properties of atoms on surfaces depend sensitively on their bonding environment
and thus provide valuable insight into the local geometry and chemical binding at the …

We report on dynamical flipping of buckled dimers on the Si (001) surface at 5 K. A c (4× 2)
ordering of the buckled dimers has been observed to fluctuate at 5 K by using low …

Recent studies of the surface dynamics of Al (001) and Cu (111) based on density functional
perturbation theory have substantiated the existence of subsurface optical phonon …
