“…With both the electrostatic field and HF field acting concurrently on the CNT cold cathode, a modulated electron beam is emitted from it. In [20], the modulated electron beam was used successfully to drive a Kaband disc-loaded waveguide structure extended interaction oscillator (EIO) to generate coherent radiation and the modulation electron beam is more easily to stimulate HF circuit by contrast with a linear electron beam. Meanwhile, using the modulation electron beam to excite HF system, an identical frequency amplified output signal can be obtained.…”

An extended interaction frequency‐locking oscillator based on carbon nanotube (CNT) cold cathode is proposed to overcome locked‐frequency limits of the conventional oscillator. Compared with the conventional oscillators, the oscillation frequency is locked by a modulation electron beam, which can be obtained in a field emission CNT cold cathode electron gun. The frequency‐locking signal does not enter the high‐frequency (HF) system but imposes an additional HF electric field on the cathode surface by a microstrip structure, which consumes considerably less power to lock the oscillation frequency. A ladder structure extended interaction oscillator operating in 2π mode is numerically investigated by three‐dimensional Particle‐In‐Cell simulation code. By analysing the impacts of different frequency‐locking power on the locked ranges, the results show that the average output power of 30.6 W is achieved at 35.11 GHz when the frequency‐locking power consumption is 460 mW. The 3‐dB bandwidth of a frequency‐locking region reaches 100 MHz.

Interest in the field of carbon nanotubes is due to unique physical properties and to significant prospects for applied applications. In this review, the quantum nanostructures with outstanding electrical properties are studied on electron emission performance optimization of carbon nanotubes with the factors affecting aligning as mechanical elasticity in bending related to electronic structure. The phenomenon of field emission producing current when an electric field is applied to a conductor is also discussed. The carbon nanotubes applications in nanotechnology are clarified in this work and it can be metallic or semiconductor depending on diameter and chirality with high emission and conductivity properties to create electronic devices.
