FIELD: electronic technology.
SUBSTANCE: invention relates to the field of electronic technology and can be used in the manufacture of products of light-indicating equipment and emission electronics based on field emission of multi-pointed carbon structures. Material for the manufacture of a multi-pointed field-emission cathode contains glassy carbon with nanopores filled with cesium atoms by the doping method with a concentration of cesium atoms determined by the size of nanopores.
EFFECT: invention makes it possible to increase the efficiency of multi-pointed field-emission cathodes by regulating the emission properties of glass carbon.
