We used molecular dynamics to study the segregation and coalescence of helium bubbles
in tungsten. We found that, similar to the case of tungsten surface, small mobile helium …

An exhaustive analysis based on density functional theory (DFT) simulations of the
accumulation of several He atoms has been performed at the vicinity of a non-coherent W< …

In the present work, the growth of helium bubble at Σ3 (112)[110], Σ5 (013)[100] and Σ13
(015)[100] three grain boundaries in tungsten is studied using molecular dynamics …

In this paper, we report on ab initio simulations results focused on completing a thorough
energetic, structural, charge and mobility analysis of the synergistic behaviour of diverse …

Helium solutions at eight symmetric tilt grain boundaries (GBs) in tungsten (W) have been
investigated through first-principles calculations. The GBs are constructed by the …

Density function theory calculations have been performed to study the stability of small
helium-vacancy (He-V) complexes near tungsten (W) surfaces of different orientations. The …

We report results of object kinetic Monte Carlo (OKMC) simulations to understand the effect
of helium flux on the near-surface helium accumulation in plasma-facing tungsten, which is …

Nanostructure formation on tungsten (W) surfaces under helium (He) irradiation is a unique
and interesting phenomenon that directly impacts the performance and lifetime of W-based …

We provide a description of the dependence on surface crystallographic orientation and
temperature of the segregation of helium implanted with energies consistent with low-energy …

We report a systematic energetic analysis of helium-related defect interactions that mediate
helium (He) segregation on surfaces of plasma-exposed tungsten at different levels of He …
