impurity (n)

If doping is performed with a pentavalent impurity atom, one of the valence electrons is unable to find a binding partner and remains in the crystal structure as a free electron.

Doping is the process of deliberately altering a semi-conductor's conductivity or crystal structure by introducing a small number of impurity atoms into high-purity semi-conductor crystals.
