Deuterium retention in recrystallized tungsten exposed to high-flux plasma with fluences up to 1 × 1029 m−2

Nuclear Fusion
Plasma fluence at the divertor of a future magnetic confinement fusion device can accumulate up to ∼10 ^28 –10 ^29 m ^−2 per year. Yet hydrogen isotope (HI) retention under such high-fluence plasma exposure has been rarely reported.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Selective formation of tungsten nanowires

Nanoscale Research Letters, 2011
We report on a process for fabricating self-aligned tungsten (W) nanowires with polycrystalline silicon core. Tungsten nanowires as thin as 10 nm were formed by utilizing polysilicon sidewall transfer technology followed by selective deposition of ...
