Abstract
Aligned nitrogen-containing carbon nanofibers consisting of polymerized "na nobells" have been grown on a large scale using microwave plasma-assisted c hemical-vapor deposition with a mixture of methane and nitrogen. A greater part of the fiber surface consists of open ends of the graphitic sheets. A side-emission mechanism is proposed. A low-threshold field of 1.0 V/mu m an d a high-emission current density of 200 mA/cm(2) for an applied field of 5 -6 V/mu m were achieved, implying that the materials have a high potential for future application as electron field emitters, especially in flat-panel displays.
