Nitrogen-doped carbon nanotubular fibers with a very high nitrogen concentration (approximately 20 at.%) were synthesized through the aerosol-assisted decomposition of dimethylformamide in the presence of catalyst. The synthesized fibers process a novel "pearl necklace-like" morphology and exhibit an excellent field emission performance.
