Morphology control of rapid grown vertically aligned carbon nanotube forest for fiber spinning is reported. Thermal chemical vapor deposition (CVD) system at around 700°C was used with a catalyst of iron catalyst films deposited on thin alumina supporting layers. Acetylene gas diluted with hydrogen and nitrogen was used as a carbon source. The morphology of carbon nanotube was observed by scanning...
This paper presents direct growth of horizontally aligned carbon nanotubes (CNTs) between two predefined various inter-spacing up to tens of microns of electrodes (pads) and its use as CNT field-effect transistors (CNT-FETs). The catalytic metals were prepared, consisting of iron (Fe), aluminum (Al) and platinum (Pt) triple layers, on the thermal silicon oxide substrate (Pt/Al/Fe/SiO2). Scanning electron...
