Multilayer photoreceptor device, layers of which have different lattice parameters

Résumé

The invention relates to a photoreceptor device, with a first crystalline, semi-conductive material, comprising a first lattice parameter, and a second crystalline, semi-conductive material, deposited on the first material and comprising a second lattice parameter, different from the first lattice parameter. In particular, the device comprises an interface layer between the first and second materials, made from an amorphous material and structured to comprise regularly spaced apart openings in the plane of the layer. The second material comprises protuberances coming out of the openings of the interface layer and forming separated crystal grains, each grain comprising a plurality of facets forming at least one angle relative to one another.
