STEM image showing the edge-on view configuration of an h-BN multilayer. a Schematic of a STEM investigation of the h-BN multilayer, the incident electron beam was parallel with its \([11\bar 20]\) crystallographic axis (the zigzag edge of the h-BN layer). b Cross-sectional schematic of the armchair edge-on view of h-BN multilayer. The red atoms represent boron atoms while the blue ones represent nitrogen atoms. c STEM-MAADF image, postprocessed by a Wiener Filter, showing the edge-on view configuration γ of an h-BN multilayer. Scale bar in (c) indicates 1 nm. d Profiles of image intensity along the red and blue arrows marked in (c), showing the stacking sequence in h-BN. Their average peak-to-peak distances are ~2.26 Å, which are in agreement with the lattice spacing of h-BN. The synchronism of the peak intensity along the arrows demonstrates the stacking structure of h-BN must be either AA′ or AA
