Phonon-Assisted Electron Emission from Individual Carbon Nanotubes

Nano Letters, 2011
A question of how electrons can escape from one-atom-thick surfaces has seldom been studied and is still not properly answered. Herein, lateral electron emission from a one-atom-thick surface is thoroughly studied for the first time.

Electron emission from nanostructures

Microelectronics Journal, 2003
Stable electron emission sources have been produced in plasma-etched single crystal silicon, coated with ultra-thin amorphous diamond, using a vacuum carbon arc source, at room temperature. Diamond films have been characterised using spectroscopy, EDX and high-resolution transmission electron microscopy.

Simulation of convoy-electron emission

Physical Review A, 1992
We present a microscopic simulation of convoy-electron production and transport through solids. Using a classical transport theory, we calculate the forward-ejected electron spectrum for 3-MeV/u H{sup 0} projectiles traversing carbon foils of different thicknesses.

Secondary electron field emission

Physica Status Solidi (a), 1988
Secondary electron field emission (SEFE) is based on Fowler-Nordheim tunneling from conducting substrates into thin insulating layers due to their strongly positive charging-up during electron bombardment. This self-consistent charging-up process is demonstrated by a computer simulation.

Electron emission microscope for use in electron emission sites observations

Applied Surface Science, 1999
An electron emission microscope (EEM) constructed for electron emission sites observations is presented. This EEM consists of three unipotential lenses, a microchannel plate, and a phosphor screen, and has the advantage that it enables the observation of electron emission sites of not only a sharp point cathode, such as a field emitter, but also a ...
