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, donorska primesa
Definition:
Silicijum ima 4 valentna elektrona u najvišem energetskom opsegu. Ako se silicijumu doda mala količina primesa od materijala koji ima pet valentnih elektrona (fosfor, arsen ili drugi elementi 5. grupe), pojaviće se višak slobodnih elektrona koji znatno povećava provodnost silicijuma.Takve primese se nazivaju donorske primese jer daju elektrone, a tako dopirani silicijum se naziva n-tip silicijuma, jer ima više slobodnih nosilaca negativnog naelektrisanja (elektrona) nego šupljina. Tipična koncentracija primesa je mala i iznosi oko 1023 atoma m3 , ali je za 6 do 7 redova veličine veća od sopstvene koncentracije nosilaca.

Definition from ETF Beograd:
Silicijum ima 4 valentna elektrona u najvišem energetskom opsegu. Ako se silicijumu doda mala količina primesa od materijala koji ima pet valentnih elektrona (fosfor, arsen ili drugi elementi 5. grupe), pojaviće se višak slobodnih elektrona koji znatno povećava provodnost silicijuma.Takve primese se nazivaju donorske primese jer daju elektrone, a tako dopirani silicijum se naziva n-tip silicijuma, jer ima više slobodnih nosilaca negativnog naelektrisanja (elektrona) nego šupljina. Tipična koncentracija primesa je mala i iznosi oko 1023 atoma m3 , ali je za 6 do 7 redova veličine veća od sopstvene koncentracije nosilaca.

Example sentence(s):
  • Donor - atom nečistoće koji povećava koncentraciju elektrona, dopant n-tipa. Materijal n-tipa - donorom dopiran materijal, poluprovodnik koji sadrži više elektrona od šupljina. - Fak. teh. nauka NS - Kat. za elektroniku  
  • Kod poluprovodnika n-tipa dodali smo donorske primese. Donorska primesa ima elektron viška koji ne učestvuje u vezama sa okolnim atomima poluprovodnika tako da se zahvaljujući njima stvara višak negativnih naelektrisanja u poluprovodniku. Kod poluprovodnika n-tipa elektroni predstavljaju tzv. većinske nosice naelektrisanja a šupljine manjinske nosioce. - Wikipedia
