FIELD: chemistry.
SUBSTANCE: invention can be used in electronics and nanotechnology. The method of producing material for a field-emission cathode based on carbon nanotubes involves deposition of modifying material - molybdenum disulphide on the surface of the nanotubes from a mixture of thiourea solution and ammonium molybdate in a closed volume for 1-3 days at 180-250°C.
EFFECT: invention simplifies the method of producing material for a field-emission cathode, and obtain material characterised by low electron emission threshold voltage, improved field emission of nanotubes and high density of emission current.
