Online steering systems allow one to retrieve application data like intermediate results for visualization, and to modify parameters during the run-time of the application. While most steering systems use a client/server paradigm, online steering can

The stopping power and straggling of ions in channeling and blocking directions depend on multiple scattering and impact parameter dependent effects. Therefore, the extraction of high-resolution depth profiles of single crystals based on simulation o

In the present work, we have studied the influence of lateral interactions between adatoms (atoms adsorbed on a lattice–gas surface) on their surface mobility. In addition, we have investigated fluctuations of the adatom surface coverage and of the

A two-dimensional lattice-gas model with square symmetry is investigated by using the real-space renormalization group (RSRG) approach with blocks of different size and symmetries. It has been shown that the precision of the method depends strongly n

High-resolution medium-energy ion scattering (MEIS) has been used to investigate the segregation of arsenic and sulfur on the (100) oriented surface of a body-centered cubic Fe–9% W(100) single crystal containing 53 wt-ppm As and 10 wt-ppm S. The s

Surface segregation on (100) oriented single crystal surfaces of the alloy Fe–25%Cr–2%Ni–0.14%Sb–N,S has been investigated by means of Auger electron spectroscopy (AES), low energy electron diffraction (LEED) and X-ray photoelectron spectrosc

Antimony has frequently been reported to cause temper embrittlement induced by grain boundary segregation in steels containing both nickel and chromium. In order to study the interdependent segregation behaviour of antimony and nickel and the effect

Tracer and collective diffusion of repulsively interacting particles adsorbed on a random AB alloy surface (Nieto, Uebing, Eur. Phys. J. B 1 (1998) 523) are studied by means of Monte Carlo modelling. Adsorption isotherms and the thermodynamic factors

We analyze the collective surface diffusion behavior of atoms adsorbed on a two-dimensional lattice-gas model with triangular symmetry in the presence of a second order phase transition. For this purpose we have studied several physical quantities wh
