5. We carried out ab initio calculations on some oligomeric models of the atomic cloth. The results showed that the LUMO is mainly distributed on the PD chains, whereas the HOMO is on the PA chains. If the picture presented in Figure 2 is assumed to be due to the LUMO, the brighter lines correspond to the PD chains, and the darker lines to the PA chains. However, this tentative assignment does not matter for the following discussion on the structure of the atomic cloth.
6. We compared our STM images with the artifact images reported in C. R. Clemmer, T. P. Beebe, Jr., Science 1991, 251, 640-642 and H. Chang, A. J. Bard, Langmuir 1991, 7, 1143-1153, which were ascribed to the cleavage steps, strands, and small particles of HOPG. Our STM image, however, has a long periodicity and is different from the artifact images.

8. Reversed STM images were observed upon changing the bias voltage; that is, PD and PA chains were dark, and alkyl chains bright. Nevertheless, there was no distinct feature corresponding to the latter chains but the undulation of contrast due to the former chains with periodicity 2 D. The image due to graphite was not observed either.
