Abstract:
A photodetection device includes a pixel matrix in which each pixel includes a barrier photodetector. The pixel matrix includes an absorption layer, a barrier layer, a contact layer, and at least one separation element to delimit the pixels. At least one separation element extends above the contact layer, and forms at least one depletion zone that extends locally in the contact layer, to block the lateral circulation of charge carriers.
