Total secondary-electron yield

  "id": "MLC-T-CHM-012150",
  "term": "Total secondary-electron yield",
  "field": "Chemistry",
  "definition": "The ratio of all electrons leaving a sample, both true secondary electrons and backscattered primary electrons, to the electrons striking it at a chosen beam energy and incidence angle, written σ = δ + η, with δ the secondary-electron yield and η the backscattering coefficient. True secondary electrons are those with energies of 50 eV or less. The name is often shortened to secondary-electron yield, which is easily confused with δ.",
