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

luovuttaja


Definition from own experience or research:
Luovuttaja eli donori on atomi tai molekyyli, joka jossakin reaktiossa luovuttaa vastaanottajalle elektronin tai atomiryhmän.

Example sentence(s):
  • Resonanssienergiasiirto (resonance energy transfer, RET) on prosessi, jossa energia siirtyy kahden samantaajuuksisen värähtelijän (älä sekoita värähtelyenergiatasoihin!) välillä. Toinen värähtelijöistä eli molekyyleistä luovuttaa energiaa ja on siis luovuttaja eli donori (D). Toinen puolestaan ottaa energiaa vastaan eli on vastaanottaja eli akseptori (A). - HUT  
  • Antimonilla, arseenilla tai fosforilla saadaan puolijohde muuttumaan N-johtavaksi. Seostusatomeja kutsutaan luovuttaja- eli donoriatomeiksi. Koska puhtaan puolijohteen kiderakenteeseessa vallitsee oktetti, jää jokaista sekoitettua V ryhmän atomia kohden ylimääräinen elektroni, joka vaeltaa puolijohteessa jo huoneenlämpötilassa. Elektroni kuljettaa mukanaan sähkövarausta. Seostetun puolijohteen johtavuutta hallitaan seostettavien atomien lukumäärällä. - TOKEM
