This work is to consider the thermoelectric effect based on the vertically aligned carbon nanotube carpets (VACNTs) and vertically aligned iron-filled CNTs (Fe-filled VacNts) have been grown using a chemical vapor deposition (CVD) method. The results show the Seebeck coefficient can be improved by controlling the layer number of Fe-filled VACNTs. It found the Seebeck coefficient of the single layer...
The effects of growth time on synthesizing of carbon nanotubes were reported. Prepared different forms of carbon nanotubes on silicon substrates by local heating chemical vapor deposition. The results showed that most of carbon nanotubes grew out with small diameter (60–80nm) and thinner in the case of short growth time (30s); when the growth time increased to 10 min or even longer, most of carbon...
This work presents the methodology to synthesize single-walled carbon nanotubes and place them directly on paper utilizing a micro chemical vapor deposition (μCVD) system. In contrast to conventional CNTs (carbon nanotubes) synthesis in high temperature furnaces, the technique of μCVD with localized heating provides the foundation for the direct growth of CNTs on paper. Experimentally, self-aligned...
Pulsed thermionic emission from multiwalled carbon nanotube fibers has been demonstrated. From fibers with diameter of 150 μm we obtained an emission current of 16 μA at a repetition rate of 1 kHz. A comparison between our CNT fibers and a tungsten filament is also presented.
