摘要：

Bamboo shaped multiwalled carbon nanotubes (MWCNTs) were grown using iron (Fe) catalyst over aluminum (Al) film by microwave plasma enhanced chemical vapour deposition. The effect of nitrogen plasma in the modification of the microstructure has been investigated. Field emission from pristine MWCNTs and bamboo shaped MWCNTs has been investigated. The turn-on field for bamboo shaped MWCNTs was (1.17 V/mu m) which is smaller as compared to pristine MWCNTs (1.42 V/um) and thus shows better emission properties.
