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)

Примесни атоми, които лесно отдават електрони се наричат донори.
Example sentences:
Антимон (Sb), арсен (As), фосфор (Р)-използват се като петвалентни донори. (Wikipedia)
Полупроводници, в които проводимостта се определя от получените от донорите свободни електрони, се наричат полупроводници с електронна (n–тип) проводимост. (Лекция)
При примесните полупроводници донорите и акцепторите са преди всичко от следните групи на периодичната система: a) донори -III; акцептори-V; б) донори -V; акцептори-III; (Изпитна тема)
