Donor Atoms

Author: Hans Lohninger

A donor atom is a pentavalent atom (e.g. arsenic) which is added as an impurity. These impurities donate electrons to the germanium crystal. Such crystals are referred to as N-type because conduction is carried on by means of the negatively charged electrons, contributed by the donor atoms.
