Effect of ion bombardment on the synthesis of vertically aligned single-walled carbon nanotubes by plasma-enhanced chemical vapor deposition.
The synthesis of vertically aligned single-walled carbon nanotubes (VA-SWNTs) by plasma-enhanced chemical vapor deposition (PECVD) was achieved at 500-600 °C, using ethylene as the carbon source and 1 nm Fe film as the catalyst. For growth of high-quality VA-SWNTs in a plasma sheath, it is crucial to alleviate the undesirable ion bombardment etching effects by the optimization of plasma input p...
متن کاملOptimized Conditions for Catalytic Chemical Vapor Deposition of Vertically Aligned Carbon Nanotubes
Here, we have synthesized vertically aligned carbon nanotubes (VA-CNTs), using chemical vapor deposition (CVD) method. Cobalt and ethanol are used as the catalyst and the carbon source, respectively. The effects of ethanol flow rate, thickness of Co catalyst film, and growth time on the properties of the carbon nanotube growth are investigated. The results show that the flow rate of ethanol and...

متن کاملLarge-Scale Synthesis of Rings of Bundled Single-Walled Carbon Nanotubes by Floating Chemical Vapor Deposition
Since their discovery, single-walled carbon nanotubes (SWNTs) have attracted considerable attention due to their unique chemical and physical properties, as well as their promise in the area of materials chemistry. Using previously reported synthetic methods, carbon nanotubes (CNTs) are always grown as long strings, and this string shape largely determines their properties. CNTs with annular ge...
متن کاملDirect synthesis of single-walled carbon nanotubes bridging metal electrodes by laser-assisted chemical vapor deposition
Direct synthesis of single-walled carbon nanotubes SWNTs bridging prepatterned Mo electrodes has been achieved using laser-assisted chemical vapor deposition LCVD . The synthesized SWNTs are found predominantly semiconducting. By controlling the spot size of the focused laser beam, synthesis of SWNTs can be achieved in a localized manner, which is governed by the thermal and optical properties ...
