Figure 2 : Void thickness growth in Stage 2 over a dose range of 2.27 to 2.36 d.p.a.

From: In-situ atomic-scale observation of irradiation-induced void formation

Figure 2

(a) First vacancy layer nucleates on the top of the (0001) facet as indicated by the yellow arrow. (b) The spreading of the vacancy layer on the (0001) facet, the size of the vacancy layer is designated by the dashed lines. (c) Vacancy layer extends over the whole (0001) facet surface. (d) Subsequent nucleation of a new vacancy layer (see Supplementary Movie 3 for more details). Scale bar, 5 nm.
