Growth of vertically aligned nitrogen-doped carbon nanotubes: control of the nitrogen content over the temperature range 900-1100 degree C

Article Abstract:

Nitrogen-doped carbon nanotubes are grown vertically aligned on the iron nanoparticles deposited on silicon substrates, by thermal chemical vapor deposition of methane/ammonia and acetylene/ammonia mixtures in the temperature range of 900-1100 degree C. The growth of nitrogen-doped carbon nanotubes is explained using a base growth mechanism proposed for carbon nanotubes.

Vertically aligned carbon nanotubes grown by pyrolysis of iron, cobalt, and nickel phthalocyanines

Article Abstract:

The growth properties of vertically aligned carbon nanotubes (CNTs) depending on the pyrolysis source and temperature are investigated. As the temperature increases from 700 to 1000 degree C, the growth rate of CNTs increases by a factor of approximately 45 and the average diameter increases from 30 to 80 nm.

Heterostructures of ZnO nanorods with various one-dimensional nanostructures

Article Abstract:

The process of growing high-density ZnO on pregrown one-dimensional nanostructures via thermal chemical vapor deposition of Zn is described. It is demonstrated through the use of carbon nanotubes, GaN nanowires, GaP nanowires, SiC nanowires, and SiC core-C shell coaxial nanocables.
