|Title:||An Intense Source of Monochromatic Electrons: Photoemission from GaAs|
|Published:||January 01, 1984|
|Abstract:||Measurements of intensity and width of the energy distribution for photoemission from negative electron affinity GaAs have been made as a function of surface preparation and temperature. Energy distributions as narrow as 31 meV (full width at half-maximum) have been obtained. The measured currents are compared to those which are currently available by coupling thermionic cathodes with electron monochromators and found to be at least 10 times as intense for distributions of equivalent width.|
