Fig. 3: Triangle-shaped defects in helium implanted Zr.
From: Two-dimensional vacancy platelets as precursors for basal dislocation loops in hexagonal zirconium
a and b Profuse triangle-shaped defects and <a> loops (with edge-on orientation) co-exist in Zr. Red arrows label the <a> interstitial loops and yellow arrows mark the <a> vacancy loops. The viewing direction is [0001]. c The triangle-shaped defect has equilateral edges along the prismatic planes (defocus of −1000 nm). d The size distribution of TVPs. 255 TVPs were involved in the statistics.
