Abstract
A light-emitting device comprises a set of nanowires over the whole surface of a substrate, comprising at least a first series of first nanowires and a second series of second nanowires; the first series comprising first nanowires emitting light under electrical control, connected between a first and a second type of electrical contact to emit light under electrical control, the first nanowires covered by at least one conducting layer transparent at the wavelength of the light-emitting device, layer in contact with the first type of electrical contact; the second series comprising second nanowires, encapsulated in a layer of metal allowing the first electrical contact to be formed; the second electrical contact being on the back face of the substrate, opposite to the face comprising the nanowires, and provided by a conducting layer facing the first series of nanowires. A method of fabrication of the light-emitting device is provided.
