Growth of Single-Walled Carbon Nanotubes with Size-Controlled Catalysts

ORAL

Abstract

A single-walled carbon nanotube (SWNT) growth system has been developed with chlorine-containing gas to control the size of catalysts during growth. The role of catalyst size has been studied with respect its effects on SWNT growth, such as random surface growth, organized vertical growth and SWNT seeds re-growth. The effect of catalyst size on SWNT etching will also be reported.
