Figure 3: Migration of trefoil defect in TMDs.
From: Three-fold rotational defects in two-dimensional transition metal dichalcogenides
(a,b) T1 defect migration in WSe2. The sequential STEM images were carefully aligned according to the vicinal large cluster (not shown) using the ImageJ software. Two Se divacancies (yellow and blue polygons) are stable in the consecutive frames, and used as references. (c–e) The migration model of T1 defect glides a lattice constant distance towards the a1 direction. Scale bar, 0.5 nm.
