Figure 3
a Lattice image of the lamella and partial epitaxial MTP of the same sample as in Fig. 1but taken after electron irradiation for 15 min. Magnified images from the areasb,c, andd coupled with 2-D Fourier transform of thesquare regions inset showing that the lamellae fragments rolled up around a MTP with partial epitaxial relationship, as schematically indexed, in (b), varied interspacing of the lamellar layer due to relaxation/rolling in (c), and zigzag suture zone (arrow) of the rolled fragments in (d)
