Left-hand side: Height profiles of the seven measured positions along an SWCNTs bundle. Right-hand side: AFM topography together with an approximation of the far-field spot area (green ellipse), diffraction-limited area (green circle), the near-field area (small blue circle), and the y-polarization direction of the incident laser. ( A ), ( B ), and ( C ) denote the three different bundles observed in the AFM topography. This notation is used in the RBM discussion part.
