Abstract :
The feasibility of terahertz wave radiation emitted form carbon nanotube has been studied based on the simple tight-binding theory. The properties of terahertz wave and the current distribution on carbon nanotube have been characterized. The radiation efficiency of carbon nanotube bundles has been compared with that of single walled carbon nanotube. The result shows the efficiency of single walled carbon nanobue bundle dipole antennas is much higher than that of a single walled carbon nanotue dipole antenna.
