|Title: ||Sintesi e caratterizzazione delle proprietà di emissione di campo di materiali nanostrutturati a base carbonio|
|Authors: ||Terranova, Maria Letizia|
|Issue Date: ||2-Feb-2009 |
|Abstract: ||Due to their novel properties, nanostructured carbon materials are concentrating more and more efforts within the scientific community. The latest members of this ever increasing family, carbon nanotubes, have been indicated as the most interesting and promising material both from a purely scientific and technological point of view. Field emission based devices are considered their closest to market technological application. Synthesis and characterization of such structures represents, therefore, key tasks in material science research.
Within such framework, the three-year work reported in this thesis face the challenge in optimizing the deposition of Single Wall Carbon Nanotubes (SWNTs), synthesizing a new hybrid nanostructured material consisting of diamond and SWNTs and investigating their field emission properties. As for the synthesis step, a modified Hot Filament Chemical Vapor Deposition set-up was used. Carbon nanopowders were used as carbon feedstock, plain and lithographica...|
