Low-Threshold Field Electron Emission from Two-Dimensional Carbon Structures

Аннотация

Particles of multilayer graphene obtained by the method of self-propagating high-temperature synthesis are proposed as an active cathode component for field electron emission. It is shown that this material makes it possible to implement a new technology for creating efficient field emitters with a developed surface. It has been established that the effect of low-threshold field electron emission is observed in this material. In pulsed electric fields, the possibility of obtaining high-current electron beams with currents up to hundreds of amperes has been confirmed.
