English term or phrase: donor
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 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
  • 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
