    • With STM and AFM we observe different types of structures on graphite. This might be the result of the different solvents applied. Another possibility could be that in case of the AFM studies, a monolayer of rosettes is initially formed, and that on top of this layer fibers are present. We have not investigated this in detail.

    • The broadening can be estimated by using a simple model based on a spherical tip apex (radius R) and a rectangular cross section of the fiber (height H) with 2(H(2R-H))/0.5 as in P. Samori, V. Francke, T. Mangel, K. Müllen, J. Rabe, Opt. Mater. 1998, 9, 390. For the present height and a terminal radius of commercial tips of 20 nm the broadening is about 29 nm. Therefore, the "true" width is obtained by subtracting the broadening from the apparent width and is about 10 nm.
