Abstract A method of synthesizing high purity carbon nanotubes vertically aligned over a large size substrate by thermal chemical vapor deposition (CVD). In the synthesis method, isolated nano-sized catalytic metal particles are formed over a substrate by etching, and purified carbon nanotubes are grown vertically aligned, from the catalytic metal particles by thermal CVD using a carbon source gas.
