Diameter 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...
متن کاملCVD 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 کاملPatterned CVD Growth of SWNTs for Device Application
Japan Several patterned growth techniques of single-walled carbon nanotubes (SWNTs) by modifing the dip-coating process are discussed. The conventional concept of using SiO2 patterned Si substrates to selectively grow 3D carbon nanotube structures can be applied to a dip-coating method followd by alcohol CVD growth. High-quality vertically aligned single-walled carbon nanotube (SWNT) patterns c...

In this research, the effect of catalyst type on the CNTs synthesis was investigated. The carbonnanotubes (CNTs) were produced on stainless steel substrates and two of catalyst with differentcharacteristics by using Thermal chemical vapor deposition (TCVD) method. The catalysts have theimportant role for the growth carbon nanotubes (CNTs). Acetylene gas (C2H2) diluted by NH3 wasused as the reac...
