Electron Beam Sources Based on Carbon Nanotube for THz Applications

  • Chapter
  • First Online:
Convergence of Terahertz Sciences in Biomedical Systems

Abstract

Performance of electron emitter plays an essential role in the detection and generation of electromagnetic wave signals. It becomes technologically challenging from spanning terahertz applications, due to the lack of sufficient power sources. The vacuum THz amplifier, such as a travelling wave tube or a klystron is practically used to increase the output power. The characteristic of these amplifiers is mainly represented by the performance of electron beam source which has to deliver a sufficient current in order to allow an amplification of the THz signal.
