Fig. 3: Identification of B and N atoms in h-BN nanoplates using force spectroscopy.

a ∆f(z) spectra measured on B and N atoms around the central region of the h-BN nanoplates with n = 3, 4, 5. b The corresponding short-range force curves calculated from (a). The minimums of force spectra are marked by triangular symbols. The contribution of long-range force has been subtracted from ∆f(z) spectra. Scale bars: 5 Å.
