The intentional alloying of semiconductor materials with controlled concentrations of donor or acceptor impurities. Dopants in semiconductors are either charge carrier donors or acceptors, and make the semiconductor either n-type (surplus electrons), or p-type (shortage of electrons).


The chemical element (impurity) added in small amounts to an otherwise pure semiconductor material to modify the electrical properties of the material.
