English term

donor

GBK English to Latvian Science Physics
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)

piejaukumu atomi (joni)

Definition from Sci-Tech Ecyclopedia:
Piemaisījuma atoms ir pusvadītāju piemaisījums, kas var ziedot vienu vai vairākus vadāmības elektronus kristālā, kas pārvēršās par jonizētiem un pozitīvi uzlādētiem.
Example sentences:
Aktīvie centri var būt gan piejaukumu atomi (joni), gan pašvielas defekti. (ABSTRACTS Of the 21th Scientific Confere)
