Donor (semiconductors)
text:
In semiconductor physics, a donor is a dopant atom that, when added to a semiconductor, can form a n-type region. For example, when silicon (Si), having four valence electrons, is to be doped as a n-type semiconductor, elements from group V like phosphorus (P) or arsenic (As) can be used because they have five valence electrons. A dopant with five valence electrons is also called a pentavalent impurity. Other pentavalent dopants are antimony (Sb) and bismuth (Bi). When substituting a Si atom in
