Abstract: We find and study the generation regime of microwave waves in a model resonator cavity based on an array of ordered semiconductor carbon nanotubes. Within the framework of the phenomenological approach, the Gunn effect was discovered for aligned carbon nanotubes with a length of 25–150 $\mu$m, the influence of the main parameters (changes in the electric field, the distance between the electrodes, the voltage at the contacts, etc.) was studied and it was shown that the electronic efficiency during lasing can reach 13%. The results obtained can be used to design new resonator structures such as compact microwave amplifiers and emitters based on ordered arrays of nanotubes.

Keywords: Gunn effect, carbon nanotube (CNT), resonator, generation.
