depletion region

1. A region in a semiconductor device, usually at the juncture of P-type and N-type materials, in which there is neither an excess of electrons nor of holes. Large depletion regions inhibit current flow.

2. See also semiconductor diode

Example Sentences

The development of surface chemistry ensures that the silicon channel is indeed modulated by the photovoltage of the colloidal quantum dot instead of being unresponsive owing to self-pinning; the colloidal quantum dot photogate directly modulates the width of the depletion region in the bulk of the channel.
