The angular distributions of atoms sputtered by the noble gas cluster ion beam from metal
surfaces are studied. The experimental results on the angular distributions of Cu and W …

Isolated tungsten nanocolumns (W-NCs) have been reported to exhibit a higher radiation
resistance than coarse grained W samples, under radiation conditions similar to those that …

The interaction of plasma with materials is critical for the fundamental understanding of non-
equilibrium processes and their wide application. Recent achievements in fusion energy …

Nanocolumnar tungsten surfaces were investigated with numerical techniques regarding
their potential to reduce sputtering by ion bombardment. We simulated a large number of …

The surface-sputtering or ion bombardment processes of solid materials have attracted
considerable attention due to their applications in materials science and technology. Here …

The continuous development of increasingly powerful supercomputers makes theory-guided
discoveries in materials and molecular sciences more achievable than ever before. On this …

Light impurity atoms (LIAs), such as hydrogen and helium, tend to aggregate at pre-existing
intrinsic point defects. This aggregation leads to detrimental effects, particularly in …

Nuclear fusion is one of the most promising concepts for future energy production, due to the
almost endless source of fuel and the lack of greenhouse effects during operation. However …

We have measured the absolute doubly differential angular sputtering yield for 20 keV Kr+
impacting a polycrystalline Cu slab at an incidence angle of θ i= 45 relative to the surface …

This study investigates the sputtering properties of nano-columnar tungsten surfaces under
2 keV D 2+ irradiation. It was conducted both by performing experiments in a highly sensitive …
