Fig. 2

a High-resolution nc-AFM image of h-BN nanoplate with n = 4. Scale bar: 3 Å. b Frequency shift (Δf) line profile recorded along the white arrow in a at z = 0 pm. c Line map of Δf(z) along the same trace in (a). Data are recorded in constant-height AFM mode shown for various tip-sample separation, displayed in steps of 5 pm. Inset: Schematic illustration of the structural model and the extraction of Δfmin for each force curve. d The Δfmin trajectory along the same arrow. The value of Δfmin is extracted from the line map of (c), and the long-range force has been subtracted from Δf(z) curve before the determination of Δfmin for each ___location.
