CVD Growth of SWNTs and MD Modeling
Developments of catalytic CVD generation of single-walled carbon nanotubes (SWNTs) are reviewed with an emphasis on vertically aligned (VA) growth. Following the first realization of VA-SWNTs [1] by alcohol catalytic CVD (ACCVD) method, various techniques are reported for the vertical aligned growth such as control of water [2], point-arc microwave plasma CVD [3], molecular-beam CVD [4], hot-fi...
متن کاملPyrene-based mechanically interlocked SWNTs.
The synthesis of rotaxane-type species composed of pyrene macrocycles and SWNTs as linear components is described. Pyrene-SWNT interactions help template the ring-closing metathesis of U-shaped precursors around the nanotubes.
متن کاملStructured SWNTs and Graphene for Solar Cells
We propose the concept of structured single-walled carbon nanotubes (SWNTs) for the applications of heterojunction solar cells and dye-sensitized solar cells (DSSCs). The structure of SWNTs was controlled and modified by a simple water vapor treatment, which was originally developed by our group. Compared with the graphene-Si solar cell and the SWNT-Si solar cell using the random-oriented SWNT ...
متن کاملMolecular Dynamics in Formation Process of SWNTs
The formation mechanism of single-walled carbon nanotubes (SWNTs) was studied with the molecular dynamics simulation. Starting from randomly distributed carbon and Ni atoms, random cage structures of carbon atoms with a few Ni atoms were obtained after 6 ns simulation. Ni atoms on the random cage prohibited the complete closure and anneal of the cage structure into the fullerene structure. In t...
متن کاملDiameter and morphology control of SWNTs by alcohol CVD
The concentration of Co-Mo binary catalyst concentration and the effect on the morphology of single-walled carbon nanotubes (SWNT) was investigated by scanning electron microscopy and optical spectroscopy. We found that there is some critical concentration or catalyst density below which SWNTs will not be vertically aligned. Higher Mo concentrations resulted in vertically aligned, small-diamete...
