space-charge region (1) (of a semiconductor device )

A functional region in which the net charge density is significantly different from zero. (Ref. ANSI/IEEE Std 100.)

NOTE 1 The net charge is caused by electrons, holes, and ionized acceptors and donors.

NOTE 2 The space-charge regions of a semiconductor device include accumulation (enhancement), depletion, and inversion layers.

(2) (of a p‑n junction): A space-charge region contained between two neutral regions of types p and n.
