On the current state of field-emission electronics

Аннотация

The current state of field-emission electronics is reviewed and the basic types of field-emission cathodes (FECs) are analyzed (the results are presented in the form of diagrams). Special attention is paid to FECs made of carbon materials, which, in our opinion, are the most promising direction in the evolution of field-emission electronics. FEC utilization in modern electronic devices is illustrated by several examples. The main sections of the paper are devoted to analyzing the problems and prospects of FECs and field-emission electronics.
