English term or phrase: donor
Definition from Tyco Electronics Corporation:
A material that is intentionally added to a pure semiconductor material in order to increase the population of free electrons in that semiconductor, resulting in a net negative charge. A semiconductor that has had donor material added to it is called "n-type."

Example sentence(s):
  • If there is a higher concentration of donors than acceptors, the semiconductor is n-type and the free electron concentration is approximately the difference between the two doping concentrations. everything2.com
  • The ionization energy of a donor atom is the energy required to dissociate the electron from the atom and put it in the conduction band of the crystal. answers.com
  • The doping with foreign atoms increases the conductivity of semiconductor crystals. By installing pentavalent foreign atoms (donors) one receives electron excess conductors (n-conductor). ledshift.com

donor


Definition from U.S. Geological Survey + SNL.no:
An electron donor is a compound that gives up or donates an electron (e.g. during cellular respiration, resulting in the release of energy). (usgs.gov) NOR: En elektrondonor er et stoff som kan gi fra seg (donere) et elektron. (See also http://www.snl.no/intersjiktforbindelse)

Example sentence(s):
  • Grafitt (se karbon) har en utpreget sjiktstruktur og kan som vert virke både som elektrondonor og elektronakseptor for molekyler og ioner. - Store Norske Leksikon  
  • En elektrondonor er et stoff som kan gi fra seg (donere) et elektron. - "Spør en biolog"  

Explanation:
Seems like electron donor / elektrondonor is much used in biology (when googling) but the principle is physical (relates to atoms/electrons) and should therefore apply to other disciplines as well.
