ABSTRACTA feedback control mechanism based on infrared radiation monitoring coupled with reflectivity information was developed to control the temperature of a laser assisted chemical vapor deposition process for the growth of carbon nanotube forests. An infrared laser operating at 808 nm is focused on a silicon substrate containing a 20 nm-aluminum-oxide layer and a 1.5 nm-iron catalyst layer. The growth takes place in an argon/ hydrogen/ ethylene gaseous environment. SEM and Raman spectroscopy analysis show that good controllability and reproducibility is achieved over multiple experiments.

Multi-wall carbon nanotube (MWCNT) structures were grown on cobalt catalyst layer through Plasma Enhanced Chemical Vapor Deposition (PECVD) process. Acetylene (C2H2) and hydrogen (H2) are used as precursors during the PECVD process. The morphology structures of the MWCNTs grown under different PECVD time were investigated and characterized using Scanning Electron Microscope (SEM). The effect of the PECVD time on the MWCNT growth is studied by varying the PECVD time at 45 sec and 600 sec. The morphology structures suggest that the growth rate is proportional to the PECVD time under the similar setting condition of pressure, acetylene flow-rate and temperature.

A highly sensitive interdigitated electrode (IDE) with vertically aligned dense carbon nanotube forests directly grown on conductive supports was demonstrated by combining UV lithography and a low temperature chemical vapor deposition process (470 °C).

Carbon nanotube (CNT) is one of the most attractive nanomaterials which may be used in many potential applications of nanotechnology due to its excellent mechanical, electrical and thermal properties. We demonstrated the fabrication of carbon nanotube at the surface of anodic aluminum oxide (AAO) membrane by chemical vapor deposition (CVD) method. Acetylene was used as a hydrocarbon source and Fe as catalyst. CNT was synthesized at different temperature. The iron catalyst was confined in the holes of the AAO membrane. A variety of carbon structures such as nanotubes, helices, spiral, and hook-like curved shapes in the range of micrometer were synthesized. High graphitic multiwall carbon nanotube (MWCNT) was found at 700-750°C temperature.
