Abstract

This device for detecting electromagnetic radiation, in particular X-ray or γ-rays, includes: a sensing layer consisting of at least one material capable of interacting with said electromagnetic radiation to be detected, in order to liberate mobile charge carriers, whereof the movement generates an electric current; a substrate provided with a plurality of elementary collectors of the charge carriers thus liberated, said elementary collectors being distributed discretely; a transfer layer suitable for transferring the charge carriers liberated by the sensing layer at the elementary collectors, said layer being connected to the sensing layer; and an insulating adhesive mating layer, suitable for mating the plurality of elementary collectors and the transfer layer.
