charge-coupled device

[′chärj ¦kəp·əld di′vīs]
(electronics)
A semiconductor device wherein minority charge is stored in a spatially defined depletion region (potential well) at the surface of a semiconductor and is moved about the surface by transferring this charge to similar adjacent wells. Abbreviated CCD.

charge-coupled device

(electronics)
(CCD) A semiconductor technology used to build light-sensitive electronic devices such as cameras and image scanners. CCDs can be made to detect either colour or black-and-white. Each CCD chip consists of an array of light-sensitive photocells. The photocell is sensitised by giving it an electrical charge prior to exposure.
