Abstract
An optoelectronic device including a carrier having a face including flat butt-jointed facets inclined in relation to each other; seeds, mainly made of a first compound selected from the group including the compounds III-V, the compounds II-VI, and the compounds IV, in contact with the carrier in the region of at least some of the joints between the facets; and conical or frustoconical, wire-like three-dimensional semiconductor elements of a nanometric or micrometric size, mainly made of the first compound, on the seeds.
Claims13
An optoelectronic device comprising:
- a support comprising a surface comprising contiguous planar facets inclined with respect to one another;
- seeds, mainly made of a first compound selected from the group comprising III-V compounds, II-VI compounds, and IV compounds, in contact with the support at least some of the seams between facets, the volume of each seed being comprised within a sphere having a diameter in the range from 1 nm to 100 nm;
- and
- wire-shaped, conical, or frustoconical three-dimensional elements of nanometer-range or micrometer-range size, mainly made of said first compound, on the seeds.
A method of manufacturing an optoelectronic device, comprising the steps of:
- forming a support comprising a surface comprising contiguous planar facets inclined with respect to one another;
- forming seeds, mainly made of a first compound selected from the group comprising III-V compounds, II-VI compounds, and IV compounds, in contact with the support at least some of the seams between facets, the volume of each seed being comprised within a sphere having a diameter in the range from 1 nm to 100 nm;
- and
- forming wire-shaped, conical, or frustoconical three-dimensional elements of nanometer-range or micrometer-range size, mainly made of said first compound, on the seeds.
