Tungsten, the primary material under consideration as the divertor material in magnetic-
confinement nuclear fusion reactors, has been known for the last decade to form'fuzz'—a …

Tungsten, the material used in the plasma-facing components (PFCs) of nuclear fusion
reactors, develops a fuzz-like surface morphology under typical reactor operating conditions …

Growth of helium (He) bubbles with different initial sizes in tungsten (W) has been
investigated by performing molecular dynamics simulations. Based on the simulation results …

He bubbles can exhibit different behaviors due to their different positions in the
nanocrystalline materials. Using molecular dynamics simulations, we study the dynamic …

In this study, we show from helium (He) plasma irradiation to tantalum and iron surfaces that
morphology changes in nanoscale occur on the both metals. In particular, from systematic …

Helium (He) plasma treatment can be a versatile tool to fabricate nanostructures on a
surface and change the surface chemistry. Herein, vanadium (V) thin film is exposed to …

Tungsten (W) has been perceived as one of the most promising plasma facing materials
(PFMs) for future fusion reactors. In the past decade, its behavior under irradiation and …

We report a simulation study on the effects of helium (He) bubble size on the morphological
evolution and pattern formation on the surface of tungsten used as a plasma-facing …

We report a simulation study of the effect of He-irradiation-induced surface vacancy-adatom
pair formation on the surface morphological evolution of plasma-facing component (PFC) …

In this study, we investigated the diffusion and incidence of helium on tungsten surfaces
using first principles and molecular dynamics methods. For three common tungsten surfaces …
