Abstract

In this work, ultra long vertically aligned single wall carbon nanotubes are synthesised by Plasma enhanced chemical vapour deposition (PECVD) technique at 600 °C temperature. The presence of built-in electric field in a plasma sheath aligns the growing CNTs along the field lines. Also, PECVD method favours low temperature synthesis of VA-SWCNTs. SEM and Raman are used to characterized as grown sample. Enhanced Field emission properties of as-grown VA-SWCNTs are also studied.
