Figure 3: Dislocation migration in a 12° grain boundary.
From: Dislocation motion and grain boundary migration in two-dimensional tungsten disulphide
Dislocation glide along its Burgers vector (1,0) on its glide plane (shown by dashed lines) from a to b. Several seconds later the same dislocation glides again along (1,0) from c to d. (e–g) Structural models for the migration of a 6|8 dislocation with one S vacancy (6|8-VS). (h–j) 6|8 with initial, saddle-point and final structures in the left, middle and right panels, respectively. (k) Minimum energy paths during migration for two dislocation cores. The scale bars are 6 Å.
