Low-threshold field electron emission from two-dimensional carbon structures

Particles of multilayer graphene, obtained by the method of self-propagating high-temperature synthesis, are proposed as an active component of the cathode for field electron emission. It is shown that this material allows realizing 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 on this material. In pulsed electric fields, the possibility of obtaining high-current electron beams with currents up to hundreds of amperes has been confirmed.
