Abstract

An optoelectronic device includes at least first and second light-emitting nanowires on a support, each comprising an area for the injection of holes and an area for the injection of electrons, a series electric connection including a connection nanowire on the support, which includes a first region forming an electric path with the hole injection area of the first nanowire, a second region forming an electric path with the electron injection area of the second nanowire, and a third region enabling a current to flow between first and second regions. Also included are a first conductive area connecting the hole injection area of the first nanowire and the first region of the connection nanowire and electrically insulated from the second nanowire, and a second conductive area connecting the second region of the connection nanowire and electron injection area of the second nanowire and electrically insulated from the first nanowire.
