Transmission projection topographs of SLG crystals: sample A (top) and sample B (bottom). (a), (d) Lang topographs; (b), (c), (e), (f) synchrotron white-beam topographs. g denotes the diffraction vector; [beta]

indicates examples of diffraction contrast for $[{\bf g}\parallel {\bf l}]$ ; [gamma]

indicates examples of diffraction contrasts for $[{\bf g}\,\bot\,{\bf l}]$ (see §

4.2).
