Single-electron transistor made of multiwalled carbon nanotube using scanning probe manipulation. Applied Physics Letters. Volume 75, Issue 5. 728-730. ISSN 0003-6951 (printed). DOI: 10.1063/1...
We have studied the high-bias transport properties of the different shells that constitute a multiwalled carbon nanotube. The current is shown to be reduced as the shell diameter is decreased or the length is increased. We assign this geometrical dependence to the competition between the electron-phonon scattering process and Zener tunneling.
New materials have significant impact on development of new methods and instrumentation for chemical analysis. From the discovery of carbon nanotubes in 1991, single and multi-walled carbon nanotubes (SWCNTs and MWCNTs) -due to their high adsorption and desorption capacitieshave been employed as sorption substrates in solid-phase extraction for the preconcentration of heavy metals from diverse ...
In this paper we report on the magnetic properties of singleand multiwalled carbon nanotubes synthesized using different chemical vapour deposition methods and with variety of catalyst materials (ferromagnetic Fe, FeCo and diamagnetic Re). Different methods yield carbon nanotubes with different morphologies and different quantity of residual catalyst material. Catalyst particles are usually enc...
