depletion layer

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
depletion layer [də′plē·shən ‚lā·ər]
(electronics)
An electric double layer formed at the surface of contact between a metal and a semiconductor having different work functions, because the mobile carrier charge density is insufficient to neutralize the fixed charge density of donors and acceptors. Also known as barrier layer (deprecated); blocking layer (deprecated); space-charge layer.

Generation/recombination effects in the depletion layer by low voltages By low voltages, the depletion layer width is not negligible as was assumed by the derivation of the Shockley model.

The existence of a depletion layer is of considerable interest, since such behavior is in sharp contrast to that expected for polymer density profiles associated with the physical adsorption of homopolymers or polymers grafted to surfaces that are also adsorbing surfaces.
