From: Single adatom dynamics at monatomic steps of free-standing few-layer reduced graphene
Dynamics of single adatoms and monatomic steps with ultrasmall lateral size on the free-standing few-layer reduced graphene.
(a–f), Snapshot of HAADF STEM images at different time: 3 s (a), 54 s (b), 126 s (c), 177 s (d), 222 s (e) and 252 s (f). The atomic steps are indicated by white arrows. Each image is produced from the overlapping of 10 continuous snapshots and low-pass filtered. (g–i), Snapshot of HAADF STEM images at different time: 3 s (g), 123 s (h) and 300 s (i). Each image is low-pass filtered. Individual adatoms are highlighted by white arrows. Scale bars, 1 nm. The dynamics is also shown in Supplementary Movies S1 and S2.
