我们合成了对齐的多壁碳纳米管多层膜气溶胶辅助催化化学气相沉积通过连续注射的气溶胶含有碳和催化剂前体。每个序列都通过特定的持续时间或前体混合物来追踪，其中碳源可能富含C-13同位素标记。我们发现，任何序列都涉及在基底表面上生长一个新层，在任何预先存在的层下，通过将其抬起，给出了基础生长机制的明确证据。
We synthesized aligned multiwalled carbon nanotube multilayers by aerosol-assisted catalytic chemical vapor deposition through sequential injections of aerosols containing both carbon and catalyst precursors. Each sequence was traced by a specific duration or precursor mixture, with the carbon source being possibly enriched in C-13 isotope labels. We discovered that any sequence involved the growth of a new layer on the substrate surface, under any pre-existing one by lifting it up, giving definitive evidence of a base-growth mechanism.
