Abstract

A radiation detector includes a stack of layers along a direction Z, the stack comprising: an absorbent layer, a first contact layer, an assembly consisting of at least one intermediate layer, referred to as an intermediate assembly, an upper layer, the first contact layer and the upper layer having a plurality of detection zones and separation zones, a detection zone corresponding to a pixel of the detector, a passivation layer made from a dielectric material, arranged on the upper layer and having openings at the level of the detection zones of the upper layer, the semiconductor layers of the stack being compounds based on elements of groups IIIA and VA of the periodic table of the elements, the second material comprising the VA element antimony and the third material not comprising the VA element antimony.
