Density control of carbon nanotubes and filaments films by wet etching of catalyst particles and effects on field emission properties
TG De Monsabert, J Dijon, P Gadelle - Carbon, 2005 - Elsevier
Carbon nanotubes and filaments (CNT&F) films with controlled density were grown by low
pressure thermal chemical vapour deposition from acetylene on nickel nanoparticles.
Density control was achieved by wet etching of the catalyst particles before carbon growth.
Field emission measurements were carried out on several films with different CNT&F
densities obtained with this method. Despite strong morphological changes, only slight
differences in the field emission characteristics between the highest and the lowest density …
