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 sentences:
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
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.
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 <b><a href="http://www.snl.no/intersjiktforbindelse)" rel="nofollow noopener" target="_blank">http://www.snl.no/intersjiktforbindelse)</a></b>
Example sentences:
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")
