“…The relatively large D-band peak is observed at 1331 cm −1 , which is attributed to the carbonaceous particles, the defects in curved graphite sheet and tube surface. This is consistent with the report by Kwo, and not much different from multiwall CNT films [16]. The appearance of a D′ component (1612.9 cm −1 ) possibly resembles the slightly disordered and highly oriented pyrolitic graphite feature [17].…”

A simple process to fabricate chain-like carbon nanotube (CNT) films by microwave plasma-enhanced chemical vapor deposition (MPCVD) was developed successfully. Prior to deposition, the Ti/Al 2 O 3 substrates were ground with Fe-doped SiO 2 powder. The nano-structure of the deposited films was analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Raman spectroscopy. The field electron emission characteristics of the chain-like carbon nanotube films were measured under the vacuum of 10 −5 Pa. The low turn-on field of 0.80 V/μm and the emission current density of 8.5 mA/cm 2 at the electric field of 3.0 V/μm are obtained. Based on the above results, chain-like carbon nanotube films probably have important applications in cold cathode materials and electrode materials.

“…These are advantages over tungsten and molybdenum tip arrays, which require a vacuum of 10 Ϫ10 torr and are more difficult to fabricate (55). Nanotubes provide stable emission, long lifetimes, and low emission threshold potentials (47,50).…”

Carbon Nanotubes--the Route Toward Applications www.sciencemag.org (this information is current as of April 23, 2007 ):The following resources related to this article are available online at Many potential applications have been proposed for carbon nanotubes, including conductive and high-strength composites; energy storage and energy conversion devices; sensors; field emission displays and radiation sources; hydrogen storage media; and nanometer-sized semiconductor devices, probes, and interconnects. Some of these applications are now realized in products. Others are demonstrated in early to advanced devices, and one, hydrogen storage, is clouded by controversy. Nanotube cost, polydispersity in nanotube type, and limitations in processing and assembly methods are important barriers for some applications of single-walled nanotubes.

“…Nanotube field-emitting surfaces are comparatively easy to manufacture by screen printing nanotube pastes and do not distort in moderate vacuum (108 Torr). These are benefits over tungsten and molybdenum tip arrays, which require high vacuum of 1010 torr and are tougher to fabricate [36].…”

AbstractNanostructures are widely used in nano and micro-sized systems and devices such as biosensors, nano actuators, nano-probes, and nano-electro-mechanical systems. The complete understanding of the mechanical behavior of nanostructures is crucial for the design of nanodevices and systems. Therefore, the flexural, stability and vibration analysis of various nanostructures such as nanowires, nanotubes, nanobeams, nanoplates, graphene sheets and nanoshells has received a great attention in recent years. The focus has been made, to present the structural analysis of nanostructures under thermo-magneto-electro-mechanical loadings under various boundary and environmental conditions. This paper also provides an overview of analytical modeling methods, fabrication procedures, key challenges and future scopes of development in the direction of analysis of such structures, which will be helpful for appropriate design and analysis of nanodevices for the application in the various fields of nanotechnology.
