Fig. 4
Atomic structure and displacement fields with and without a screw dislocation. a Atomistic structure obtained by filling Cu atoms into the experimentally observed grain. b Atomistic structure following addition of a perfect screw dislocation, and c atomistic structure after energy minimization. Atoms are colored by their displacement along the (111) from their initial structure. d isosurface rendering of the experimentally imaged Cu grain. b–d are colored by displacement projected along the (111) direction in Å. e–g, histograms of the displacement field corresponding to the images in b–d
