Figure 1 : A series of HRTEM images of void length growth under electron irradiation.

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

Figure 1

(a) A void (outlined by dashed lines) nucleated near the interstitial dislocation loop. (bd) Stage 1 growth of the void, where it grew in length but not in thickness. The length growth direction is indicated by the yellow arrow. Detailed growth process is shown in Supplementary Movie 2. The specimen is irradiated over a dose range of 0.95–1.17 displacement-per-atom (d.p.a.). Scale bar, 5 nm.
