High-Density Growth of Vertically Aligned Carbon Nanotubes with High Linearity by Catalyst Preheating in Acetylene Atmosphere

摘要

Vertically aligned carbon nanotubes (CNTs) with a high number density of 2 × 20~(11)cm~(-2) were successfully synthesized by catalyst-assisted thermal chemical vapor deposition using catalyst preheated in C_2H_2 atmosphere. The synthesized CNTs were found
