An n-type semiconductor is created by doping a pure semiconductor crystal with donor impurity atoms. These donor atoms contribute extra electrons, which become mobile charge carriers. However, the crystal as a whole remains electrically neutral because the positive charges associated with the fixed donor ions are balanced by the total charge of the electrons and the atoms of the base semiconductor.
An n-type semiconductor is
