          • Definition(s)
            • Dans un semi-conducteur, atome d'une impureté pouvant donner un électron libre. L'introduction des donneurs a pour effet d'augmenter le nombre d'électrons libres dans un semi-conducteur pur et de le transformer en semi-conducteur de type N. Termium - by Fabien Champême
          • Example sentence(s)
            • Un semi-conducteur type N est un semi-conducteur intrinsèque (ex : silicium Si) dans lequel on a introduit des impuretés de type donneurs (ex : arsenic As). Ces impuretés sont ainsi appelées parce qu'elles donnent un électron à la bande de conduction pour réaliser une liaison avec le cristal semi-conducteur . - Optique pour l'ingénieur by Fabien Champême
            • Et parce que les électrons à cinq atomes ont un électron supplémentaire à « donner », il sont appelés atomes donneurs. Les matériaux ainsi formés sont appelés semiconducteurs de type N parce qu'ils contiennent un excès d'électrons négativement chargés. - Encyclopédie en ligne by Fabien Champême

          • 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 by Michal Zugec

          • Additional fields of expertise
          • 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 by

            • Антимон (Sb), арсен (As), фосфор (Р)-използват се като петвалентни донори. - Wikipedia by Ivan Klyunchev
            • Полупроводници, в които проводимостта се определя от получените от донорите свободни електрони, се наричат полупроводници с електронна (n–тип) проводимост. - Лекция by Ivan Klyunchev
            • 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 by Ivan Klyunchev
