A piece of semiconductor doped with impurities that make it amenable to donating electrons.

1: describes a semiconductor material that has negatively charged conductivity (a surplus of electrons); material with free-carriers of electricity dominated by negatively charged ions. Also see conductivity type. 2: a variety of semiconductive material in which the majority current carriers are electrons, formed when donor impurities are incorporated into the crystal structure in small concentrations.

A material in which electric charge which is carried by surplus electrons.
