Surface morphology and deuterium retention in tungsten exposed to high flux D plasma at high temperatures
TLDR
In this paper, surface modifications and deuterium retention induced in tungsten by high fluxes (1024 m−2 s−1) low energy (38 eV) D ions were studied as a function of surface temperature.About:

Mechanism for orientation dependence of blisters on W surface exposed to D plasma at low temperature
TL;DR: In this article, the orientation dependence of blister formation induced by D plasma exposure at low temperature (about 523 K) on rolled tungsten and chemical vapor deposition (CVD) W samples was studied by scanning electron microscopy and electron backscatter diffraction.

Subsurface deuterium bubble formation in W due to low-energy high flux deuterium plasma exposure
TL;DR: In this paper, the deuterium (D) bubbles formed in W exposed to high flux D plasma were researched by scanning electron microscopy and transmission electron microscope, and a layer of nano-sized bubbles were homogenously distributed in W subsurface region.
