Simple Definitions

The most important electronics terms, demystified in one place.


Our Take

Acceptors are elements added in the doping process that have one less electron in the valence shell than the substrate semiconductor material. With one less electron, this dopant “accepts” or pulls away an electron from the base semiconductor. By pulling away this extra electron, it creates a new “hole” in the semiconductor lattice. This creates a p-type semiconductor material.

Book Definition

Acceptors are trivalent impurity atoms that can take an electron. They are added during the doping process to create a p-type semiconductor.
