Science - Physics
Additional field(s): Electronics / Elect Eng
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

Definition from The Hebrew University:
Donor הוא מזהם אשר תורם לחומר אלקטרון המסוגל לנוע בחפשיות בתוך החומר ולשאת זרם חשמל.

Example sentence(s):
  • ריכוז החורים והאלקטרונים החופשיים בגביש טהור הוא גודל קבוע לכל חומר. במידה ורוצים לשנות את התנגדות הפיסה צריך לשנות את ריכוזי האלקטרונים והחורים. למטרה זו צריך להוסיף לגביש אטומים של חומרים נוספים. אטומים אלה מכונים מזהמים או סייגים. מזהמים מהעמודה החמישית נקראים תורמים (donors). ריכוז התורמים (מספר ליחידת נפח) בחומר מסומן ב Nd. מזהמים מהעמודה השלישית נקראים מקבלים (acceptors). ריכוז התורמים (מספר ליחידת נפח) בחומר מסומן ב Na. - Uniclass  

Explanation:
התרגום הוא קצת כללי אבל בהחלט השתדלתי להביא לו תימוכין מהיבט הפיזיקלי
ובמקרה הזה donor נותר במשמעו הפילנטרופי כתורם
