Abstract

On a front face of a substrate transparent to the radiation considered, pixels are confined in a stack of absorbent semi-conducting material layers by a network of channels. An insulating layer covers the bottom and the side walls of the channels. An electrically conducting layer covers the insulating layer on the bottom and on the side walls of the channels confining at least a part of the pixels. The conducting layer can be voltage polarized.
