ABSTRACTThe field emission characteristics of the Si emitters and the diamond coated Si emitters are investigated. The Fowler-Nordheim plots of the two types of Si emitters show linear slopes. It means that the I-V characteristics follow the Fowler-Nordheim relation. Field emission for the two types of diamond coated Si emitters exhibits significant enhancement both in turn-on voltage and total emission current. The Raman spectrum shows that the high intensity graphite peak is observed with diamond peak and thereby large amounts of graphite may be included in the diamond grain boundary. It seems to be thought that the graphite participates in the low field emission. However, further investigations are needed to understand whether the graphite may enhance the emission characteristics of diamond or not.

SnO2 nanowires were synthesized by thermal evaporation, and the field emission characteristics of SnO2 nanowires are investigated in detail. The results show that the turn-on field is as low as 1.39 V/μm. And the fluctuation of field emission currents is as low as 2.8% for 24 h. The results reveal that SnO2 nanowires hold promise for field emission display application.

This paper presented a novel post-treatment method of He plasma,which could effectively improve the field emission characteristics of screen-printed CNTs cathodes. Notable changes in the surface morphologies of screen-printed CNTs cathodes were investigated by scanning electron micro scope (SEM) as the f unction of treatment by He plasma.The results showed the post-treated CNTs cathodes hold lower turn-on electric field,higher field emission current density,more emission sites,and better uniformity than those of untreated ones.

The graphene double-walled carbon nanotube (DWCNT) hybrid films were prepared by vacuum filtration and screen printing. Their electron field emission properties have been studied systematically. The electron emission properties of the hybrid films are much better than those of pure DWCNT films and pure graphene films. Comparing with the screen printed films, the vacuum filtered films have many advantages, such as lower turn-on field, higher emission current density, better uniformity, better long-term stability, and stronger adhesive strength with conductive substrates. The optimized hybrid films with 20% weight ratio of graphene, which were fabricated by vacuum filtration, show the best electron emission performances with a low turn-on field of 0.50 Vμm−1(at 1 μAcm−2) and a high field enhancement factorβof 27000.
