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