Fig. 4: Plastic relaxation by growth of dislocation networks.
From: Dislocation interactions during plastic relaxation of epitaxial colloidal crystals
a Snapshots of a growing misfit dislocation network, obtained by excluding dislocation threads, are plotted for different values of h, marked in (b). Colors correspond to different types of dislocations specified in the legend. b Plastic strain profiles εp(h) obtained by either using Eq. (1) (top) or by a direct measurement εp = εtot − εe (bottom). c When predictions of Eq. (1) are plotted against the measured εp, all profiles collapse to a single line with a slope of one. b, c Legends indicate ionic strength, I (mM), and template spacing, dt. The shadows denote the variation over five distinct observation regions of a growing crystal.
