| Fig 8 3D imaging of qPlus NC-AFM (A) 3D-NC-AFM data acquisition scheme62. (B) molecular structure of diphenanthro[9, 10-b:9′, 10′-d]thiophene (DPAT) identification from 3D data set: to resolve the molecular structure from constant-height NC-AFM images, the 3D data set is displayed along three different planar cross sections. While one of them is parallel to the surface, the other two are aligned with respect to the two carbon rings that are tilted with respect to the surface (green and red)63. (C) schematic representation of the multipass method for intramolecular resolution using AFM. (D) constant-Δf NC-AFM image associated with the first line scans over a pentacene molecule adsorbed on the (101) anatase surface. (E) image of the second line scans following the topography registered during the first line scan. The offset distance the probe was approached toward the surface during the second line scan was 0.3 nm. (F) constant-Δf NC-AFM image of a C60 molecule deposited on the (101) anatase surface obtained by applying the multipass method described in the text. The inset is a ball-and-stick model of the C60 molecule. (G) image of the second line with a distance offset of 0.21 nm64 |
