Field emission from carbon layers containing very long and sparse nanotubes∕nanofilaments

Abstract: Field-emission characteristics of carbon layers with very long (up to several mm) and sparse nanotubes (nanofilaments) have been investigated. For such layers field emission current of 10μA is registered at very low average electric field Eav=0.16V∕μm and the values of the field amplification coefficient β reach 45 000. It has been found that, at electric fields corresponding to the onset of the field emission, the emitting nanotubes are stretched towards the anode. At high emission currents (exceeding 30–50μA… Show more

“…The behavior is well explained by simple electrostatic theory 13 and obeys Fowler-Nordheim behavior 14 under dc and pulsed excitations. 15 Earlier work 16 has shown increased soft x-ray emission from laser plasmas created on carbon nanotube coated targets. In addition, they are good for generating ultrashort electron bunches with proven ability to generate x-rays.…”

“…DOI 10.34077/Semicond2019-121 Регулярные массивы нанокапель высокочистого железа на подложках кремния могут быть использованы в качестве катализаторов роста углеродных нанотрубок (УНТ). Нанотрубки углерода, покрытые аморфной оболочкой могут быть использованы в качестве автоэлектронных эмиттеров с узкой областью испускания [1,2]. Эмиттеры на основе углеродных наноматериалов отличаются рядом преимуществ по сравнению с металлическими, а именно высокой яркостью и стабильностью эмиссии в течении длительного времени [3].…”
