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)

Definition from
own experience or research:
Un donor (donori, pl.) este o impuritate cu mai multi electroni de valenta decat atomii semiconductorului in care se afla. Un acceptor (acceptori, pl.) este o impuritate care poate primi electroni pentru ca are mai putini electroni de valenta decat semiconductorul in care se afla.
Example sentences:
Prin plecarea golurilor in regiunea n si a electronilor in regiunea p, vor aparea in cele doua regiuni doua sarcini electrice spatiale, de sens opus (constituite din acceptori si donori ionizati). (Wikipedia)
