Abstract

Carbon nanotube (CNT) arrays have been produced on silicon substrate by an one-step route based on the pyrolysis of mixture of the ferrocene and melamine under well-chosen synthesis condition. Transmission electron microscope (TEM) and scanning electron microscope (SEM) studies showed the products were all multi-walled CNTs that are about 50 nm in diameter and about 15 μm in length, growing outward separately and perpendicularly to the substrate. X-ray photoelectron spectroscopy (XPS) and TEM studies revealed that the CNTs were nitrogen-doped. Field emission measurement suggested that the nitrogen-doped CNT arrays begin to emit electron at electric field of 1.60 V/μm, and field emission images exhibited the high emission sites density.
