(a) Schematic of the 30° <0001>-GB, showing the left crystal with the stacks …ACAC… and the right crystal with the stacks …ABAB…. The grain boundary plane is {}. The displacement for the transition from B to C is indicated by the black arrow and is equal to a Shockley partial dislocation. (b) and (c) atomic structures of the 30° <0001>-GB in two different views. (d) to (f) Schematics of creating a 30° <0001>-GB from a single crystal via the gliding of Shockley partial dislocations. A, B, and C planes can be referred to be (111) plane stacking with respect to face centered cubic structure. The x-axis is along
, the y-axis is along
, and the z-axis is along [0001]. Atoms in (b) and (c) are colored according to their excess energy.
