lithium-drifted silicon detector

[′lith·ē·əm ¦drif·təd ′sil·ə·kən di′tek·tər]
(nucleonics)
A type of junction detector fabricated by applying a reverse bias to a pn junction consisting of a lithium-diffused n-type region on p-type silicon, causing the lithium ions to migrate toward the negative side and to compensate negative ions, fixed in the silicon crystal lattice, to create a wide depletion layer.
