Iron silicide root formation in Carbon nanotubes grown by microwave PECVD

Article Abstract:

The microstructure and growth mechanism of microwave plasma enhanced vapor deposition (PECVD) grown carbon nanotubes (CNTs) using Fe catalysts is analyzed. Iron silicide roots penetrating into the silicon substrate are observed thus assisting in the attachment of the catalyst particles to the substrate and helping in the evolution of catalyst particle morphology and resulting base growth mode also the microwave PECVD grown CNTs exhibit superior electrical and thermal transport properties over other PECVD processes.

Enhanced photoluminescence from very thin double-wall carbon nanotubes synthesized by the zeolite-CCVD method

Article Abstract:

Photoluminescence (PL) from purified (>90%) double-wall carbon nanotubes (DWNTs), which are synthesized by zeolite catalyst-supported chemical vapor deposition (zeolite-CCVD) of very small diameters (0.8-nm average inner tube) is presented. The PL contour mappings of various ratios (1-90%) of double-versus single-wall carbon nanotubes by thermal oxidation enabled to unambiguously identify the chirality of inner tubes for the DWNTs synthesized.

Thermogravimetric analysis of synthesis variation effects on CVD generated multiwalled carbon nanotubes

Article Abstract:

A thermogravimetrical study is conducted to determine the oxidation behaviors of chemical vapour deposition (CVD)-grown multiwalled carbon nanotubes with varying synthesis conditions. The results suggest that the catalyst type and synthesis temperature have a significant impact upon the nanotube stability and differing levels of crystalline perfection in the nanotubes.
