Controlled Geometry Formation of the Carbon Coils by the Substrate Pretreatment

Figure 2

Photographs of (a) the prepared substrates by the various pretreatment methods and (b) the as-grown carbon coils on these substrates after 60 minutes deposition reaction. Two pieces were shown for each sample. The small piece was used for FESEM investigation.
