Abstract:
A thermal electron emitter includes at least one carbon nanotube twisted wire and a plurality of electron emission particles mixed with the twisted wire. The carbon nanotube twisted wire comprises a plurality of carbon nanotubes. A work function of the electron emission particles is lower than the work function of the carbon nanotubes. A thermal electron emission device using the thermal electron emitter is also related.
