- Definition(s)
- Der Donator ist das Atom, mit dem der Halbleiterwerkstoff für die n-Schicht verunreinigt wird. ELKO - by Andrea Flaßbeck (X)
- Example sentence(s)
- Die Dotierung mit Fremdatomen erhöht die Leitfähigkeit von Halbleiterkristallen. Durch Einbau von fünfwertigen Fremdatomen (Donatoren) erhält man Elektronenüberschussleiter (n-Leiter). - Ledshift
by Andrea Flaßbeck (X) - Man bezeichnet ein solches Atom daher als Donator (lat. „donare“ schenken, geben). - Google Books
by Andrea Flaßbeck (X) - Donatoren bzw. Donatorenatome sind zum Beispiel:
* Phosphor (P) in Form von PH3, PCl3 oder POCl3
* Arsen (As) in Form von AsH3 oder As2O5
* Antimon (Sb) - ELKO

- Definition(s)
- Pridaním malého množstva prímesí do polovodičov sa výrazne menia ich vlastnosti. Pridaním prvku ktorý má viac valenčných elektrónov než pôvodný polovodič - donor - sa zvyšuje pravdepodobnosť, že sa akoby „nadbytočný“ elektrón odtrhne. Podobne pri prímesi s menším počtom valenčných elektrónov - akceptor - sa ľahko vytvorí diera.
Donormi vytvárame polovodič typu N a akceptormi typu P.
Wikipedia - by Michal Zugec
- Example sentence(s)
- Prímesové atómy, ktoré z polovodičovej látky tvoria polovodič typu N, nazývajú sa donory (od slova donor - dárca). Donory teda poskytujú kryštálu voľné elektróny. - Referat

- Definition(s)
- 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." Tyco Electronics Corporation
- 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
by - 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
by - 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
