Enhancement of electron field emission of vertically aligned carbon nanotubes by nitrogen plasma treatment

Ultralow field emission from thinned, open-ended, and defected carbon nanotubes by using microwave hydrogen plasma processing

“…Considering the high density of our CNTs, this FE performance is outstanding. It is far better than a great many well reported CNT emitters such as ion irradiated CNTs [4], CNT-graphene composites [12,13], element doped CNTs [14], chemically processed CNTs [15], NH 3 , oxygen, and nitrogen processed CNTs [16][17][18][19][20]. Replotting of the data as ln(J/E 2 ) versus 1/E, i.e., the F-N plots, as shown in the inset of Fig.…”

“…For example, Chen at al reported the FE properties of NH 3 plasma processed CNTs, and they found that the treated CNTs have a much lower E on than that of the untreated ones [16]. Similar strategies have also been used to improve the FE properties of CNTs, such as oxygen [17,18] and nitrogen processing [19,20]. However, there are still great efforts need to be made to further lower the E on and E th , ameliorate the FE stability, and deeply understand the FE enhancement mechanism.…”

The induction of nanographitic phase on Fe coated diamond films for the enhancement in electron field emission properties

“…The EFE properties of (Fe/UNCD) 900 films is comparable to those of as-prepared carbon nanotubes (CNTs). [21][22][23] To facilitate the comparison, the EFE properties of the as-grown and Fe- coated/annealed MCD films 15 are also plotted in Fig. 3.…”

Binder-free, high-performance carbon nanotube line emitters fabricated using mechanical clamping process

“…Many researches have clearly revealed that an individual carbon nanotube (CNT) is an excellent electron field emitter with a low turn-on field for emission, high emission current density, and longterm emission stability [1][2][3][4][5]. The superior emission characteristics stem from the unique onedimensional structure and the extraordinary properties of CNT [6][7][8][9].…”
