From: Defects in bilayer silica and graphene: common trends in diverse hexagonal two-dimensional systems
80 kV AC-HRTEM images of Stone-Wales transformations in HBS.
(a) Overview image of a disordered area of HBS. (b) Higher magnification image of the area marked in panel (a) along with a series of subsequent images of the same area showing intermediate atomic configurations during annihilation of a SW. (c) Two examples of SW transformations in crystalline HBS. The upper row: original AC-HRTEM micrographs. Lower row: same images with maximum filtering28 applied for better visibility of the defect structures.
