The work by Jana Andzane, Joseph M. Tobin, Zhonglai Li, Juris Prikulis, Mark Baxendale, HÃ¥kan Olin, Justin D. Holmes and Donats Erts has been published in a special edition of the open access journal, AZoJono* and is available in its entirety at election of Application Specific Single and Multi Walled Carbon Nanotubes. This special edition of AZoJono features a number of papers from DESYGN-IT, the project seeking to secure Europe as the international scientific leader in the design, synthesis, growth, characterisation and application of nanotubes, nanowires and nanotube arrays for industrial technology.
In their work, the conductive and field emission properties of individual single and multi-walled carbon nanotubes were assessed using an in-situ transmission electron microscope-scanning tunnelling microscope (TEM-STM) technique. The nanotubes were grown by chemical vapour and supercritical fluid deposition techniques. Experimental field emission characteristics for all carbon nanotubes investigated fitted well to the Fowler-Nordheim equation when different work functions were applied. Differences in field emission and conductive properties are analysed and related to the structure of the carbon nanotubes. The method presented can be applied in order to make in situ selection of carbon nanotubes with desired properties for specific electronic applications.
The researchers found that conductivity and field emission properties were nanotube structure dependent. The structure of the outer layers and whether or not the nanotubes were filled with C60 molecules were key factors in determining the properties of the carbon nanotubes.
hese findings make a significant contribution to the understanding of the structure/property relationships for carbon nanotubes, which in turn bring the next generation flat panel televisions and monitors a bit closer to our lounge rooms and offices. ###
