SEM images of samples produced at 1020 °C with 40 min of growth. The images correspond to the different furnace zones: S1, S2, S3, S4, S5, and S6 (see Fig. 1). Note that depending on the furnace zone, the collected material exhibits different morphologies and sizes in the carbon structures. The hottest zones correspond to zones 3 and 4. High magnification images can be seen in Fig. SI-1.
