Field electron emission of double walled carbon nanotube film prepared by drop casting method [PDF]
, 2007 Thick films of double walled carbon nanotubes (DWCN) were deposited on indium-tin-oxide (ITO) coated glass substrates by drop casting method and were studied for their field electron emission property in a parallel plate configuration using bare ITO ...

Potential Electron Emission from Metal and Insulator Surfaces
, 2007 Impact of slow ions (impact velocity < 1 a.u. = 25 keV/amu) on solid surfaces is of genuine interest in plasma- and surface physics, and related applications. Nature and intensity of the resulting inelastic processes depend both on the kinetic and the

General scaling laws of space charge effects in field emission
New Journal of Physics, 2021 The characteristics of field electron and ion emission change when the space charge formed by the emitted charge is sufficient to suppress the extracting electric field. This phenomenon is well described for planar emitting diodes by the one dimensional (

FIELD ELECTRON EMISSION FROM NANOSTRUTURED SURFACE OF CARBONIZED IRIDIUM
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2019 The characteristics of the field electron emission of the iridium tip with different carbon formations on its surface are investigated. It was found that in some cases, compared to metal emitters the carbon-coated emitter exhibits significantly greater ...
