Electron Emission from Solid Surfaces

  • K. Ertl

Abstract

Electrons are emitted from solid surfaces as a result of heating, of ion, electron and photon bombardment from the plasma, and if a sufficiently high electric field is applied. Thermal electron emission only becomes important at temperatures above 2000° C. With particle bombardment at energies in the 10 to 100 eV range, the yields are typically of the order of 0.1 to 1 except in the case of highly charged ions, where potential emission yields may be well above 1. Field electron emission may be important for the ignition of electrical arcs.
