AI Article Synopsis
- The study examines the thermal radiation emitted by a carbon nanotube (CNT) of limited length, exploring both its near-field and far-field interactions.
- It shows that metallic CNTs exhibit a discrete spectrum in the terahertz range, caused by the reflection of slowed-down surface-plasmon modes at the ends of the CNT, a phenomenon not found in semiconductor CNTs.
- The research introduces the idea of considering CNTs as thermal nanoantennas, which could have implications for nano-scale thermal management and energy harvesting.
Article Abstract
The thermal radiation from an isolated finite-length carbon nanotube (CNT) is theoretically investigated both in near- and far-field zones. The formation of the discrete spectrum in metallic CNTs in the terahertz range is demonstrated due to the reflection of strongly slowed-down surface-plasmon modes from CNT ends. The effect does not appear in semiconductor CNTs. The concept of a CNT as a thermal nanoantenna is proposed.
