摘要: An infra-red detector (10) comprises a detector region (38) and a collector region separated by a barrier region. Operation of these regions is controlled by potentials applied to respective gate electrodes (30, 34, 32), insulated from the detector, barrier and collector regions by an insulating oxide layer (36). The detector, barrier, and collector regions may be arranged on a silicon substrate (24). In operation, photo-excited electrons are generated in the detector region and these cross the barrier region for readout from the collector region.
