Diffusion-assisted growth of periodic patterns on metal surfaces
Wei Qian,Pengfei Zheng,Ning Gao,Wahyu Setyawan,Peng Chen,Xing Liu,Yang Liu,Liangting Sun,Ming Yu Liu,Tong Che,Ran Wei,Jiming Chen +11 more
TL;DR: Wang et al. as mentioned in this paper demonstrated that atom diffusion accelerated by low energy and high flux exposures is the dominant mechanism for pattern formation on tungsten surfaces, which may provide a new understanding of pattern formation.

TL;DR: In this article, the evolution of intrinsic impurity fluxes in the newly installed W divertor with respect to studying material migration is described, and a statistical analysis of transient impurity events causing significant plasma contamination and radiation losses is shown.

Formation process of tungsten nanostructure by the exposure to helium plasma under fusion relevant plasma conditions
TL;DR: In this paper, it was shown that the tungsten nanostructure is easily formed when the temperature is in the range 1000-2000 K, and the incident ion energy is higher than 20 eV.
