Abstract (en)
[origin: WO2017182450A1] The invention relates to a photoreceptor device, including at least: a first crystalline semiconductor (11) having a first lattice parameter; and a second crystalline semiconductor, deposited on the first semiconductor, and having a second lattice parameter that is different from the first lattice parameter. In particular: the device includes an interface layer (12) between the first and second semiconductors, said layer being made from an amorphous material and structured to include apertures that are regularly spaced in the plane of the layer; the second semiconductor includes protuberances that extend out of the apertures of the interface layer and that form separate crystal grains (10), each grain having a plurality of facets making at least one angle therebetween; the interface layer is made from an insulator and is of thickness smaller than 10 nm in order to form a tunnel junction between the first and second semiconductors.
