Nanotube Films

The use of carbon nanotubes (CNTs) for construction of sensors is promising. This is due to some unique characteristics of CNTs. In recent years, strain sensors built from CNT composite films have been developed; however, their low piezoresistive sensitivity (gauge factor (GF)) in in-plane strain detection is a concern compared with other strain sensors. This article reports an experimental discovery of the superior piezoresistive response of a CNT film that is free of surfactants, known as the pure CNT film. The mechanism for the high GF with the pure CNT film strain sensors is also discussed.

Nanotube Films

The field electron emission from carbon nanotube films on polycrystalline diamond films was investigated. The carbon nanotubes and diamond films on Si substrates were prepared by a conventional hot filament chemical vapour deposition. The films obtained were characterized by scanning electron microscopy and Raman spectroscopy. The field emission properties of the samples were measured in an ion-pumped vacuum chamber at a pressure of 10-6 Pa.. The experimental results showed that the field emission behaviours of carbon nanotubes/diomond films structure have greatly been improved as compared with carbon nanotubes and diamond films, respectively. A turn-on field of 1.0 V/µm and a maximum current of 500 µA at 1.5 V/µm were observed, which were lower than those of carbon nanotubes and polycrystalline diamond films, respectively. This improvement was attributed to the tip shape of sample surface, which provided an additional local increase in electric field at the tube ends.

In this paper, the Seebeck effect of mutilwalled carbon nanotube films has been studied. The carbon nanotubes were synthesized by hot filament chemical vapor deposition using Ni - Fe as a catalyst. It was found that the thermoelectromotive force (thermo emf) changed approximately linearly with the temperature at the hot end at room temperature, and the Seebeck coefficient of carbon nanotube films was about 10~50 μv/k. The experimental results were discussed in detail.

Nanotube Films

The strain-induced resistance changes of both SWNT and MWNT films have been studied. Carbon nanotubes in this study were synthesized by hot filament chemical vapor deposition. Experimental results showed that there is a striking piezoresistive effect in carbon nanotube films. The relative change in resistance of carbon nanotube films was increased with the increasing strain. In the same strain, the resistance changes of SWNT films exceed that of MWNT films. The origin of the resistance change in the films may be caused by strain-induced change in the bandgap and intertube contact resistance.
