Record 3 1992-10-29

English

Subject field(s)
  • Chemistry
  • Semiconductors (Electronics)
DEF

An impurity atom that tends to give up an electron and thereby affects the electrical conductivity of a crystal. It is used to produce N-type semiconductor material. An element with less than four valence electrons that is used as a dopant for semiconductors. Donor atoms mixed with silicon makes a P material.

French

Domaine(s)
  • Chimie
  • Semi-conducteurs (Électronique)
DEF

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.
