Abstract

We overview definitions, properties and applications of Carbon nanotubes (CNTs). We describe the CNTs lifecycle: starting with phases and requirements, going through the different synthesis methods, describing then the various purification techniques. The fundamentals of functionalization and the use of defects in CNTs are reviewed, in connection also to ion irradiation techniques. Metal oxides and other semiconducting 1D nanostructures are then considered, before entering the description of the main features of the present status of INFN-LNF research in nanoscience, focusing on CNTs, as well as on aluminium nitride NTs (AlN NTs). We conclude our review by illustrating device application criteria for many applications in different areas of the field of nanotechnology. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
