Low temperature growth of vertically aligned carbon nanotubes by thermal chemical vapor deposition

Vertically well-aligned carbon nanotubes (CNTs) are grown on Fe-deposited silicon oxide substrate at 550°C by thermal chemical vapor deposition of C 2H 2 gas. We employed two-stage heating technique that the reactants heated at 850°C in the first zone flow into the second zone maintained at 550°C fo...

Description
Summary:Vertically well-aligned carbon nanotubes (CNTs) are grown on Fe-deposited silicon oxide substrate at 550°C by thermal chemical vapor deposition of C 2H 2 gas. We employed two-stage heating technique that the reactants heated at 850°C in the first zone flow into the second zone maintained at 550°C for CNT growth. The CNTs have bamboo structure, closed tip, and defective graphite sheets.
