From: Atomic configurations at InAs partial dislocation cores associated with Z-shape faulted dipoles
Dislocation cores with opposite ions at atomic resolution.
(a) Aberration-corrected HAADF image of dislocation cores 1 and 2 as projected along the 
direction. The location of dislocation cores are indicated by blue and red arrows and the corresponding stacking sequences are overlapped. (b) Area contained in the white box in (a) shown at higher magnification. The atomic arrangements at dislocation cores and stacking faults are clearly resolved. The dumbbells nearest to the single atomic columns at dislocation cores with bond length variations are indicated by black arrow heads. The intensity line profiles at dislocation cores are labeled by white dashed arrows and the results are presented in (c) and (d), respectively. (e) and (f) Corresponding atomic models of the two regions framed by white boxes in (b). (g) Sketch of geometric relationship of the Burgers vectors and the dislocation line according to Thompson's notation.
