The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

open access: yesAdvanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

Defect production in tungsten under sub-threshold energy irradiation: role of hydrogen and surface effects

open access: yesNuclear Fusion
Despite the low solubility of hydrogen isotopes (HIs) in tungsten (W), their concentration can reach up to ∼10 at.% after low-energy plasma irradiation. This is generally attributed to the vacancies that may accommodate excessive HIs.

Role of Helium Bubbles and Voids on the Property of Nanocrystalline Tungsten [PDF]

open access: yesarXiv
This manuscript embarks on an inquiry into the influence of helium implantation on nanocrystalline tungsten, a contender for plasma-facing components (PFCs) in nuclear fusion reactors. The study underscores the inevitability of helium retention in tungsten due to the anticipated high flux of helium atoms from D-T fusion reactions in future reactors ...
