A thermionic cathode (100) comprises an individual carbon nanotube (102) attached between two electrodes (104, 106). The electrodes (104, 106) each comprise a post (110, 112) and a carbon fibre (114, 116). A gap (118) narrower than the Iength of the nanotube (102) is provided between the two carbon fibres and the carbon nanotube (102) bridges the gap. This provides an extremely efficient thermionic cathode (100).
