OPTOELECTRONIC DEVICE WITH THREE-DIMENSIONAL SEMICONDUCTOR ELEMENTS

摘要

The invention relates to an optoelectronic device (30) including three-dimensional semiconductor elements (20) predominantly made of a first compound selected from among the group consisting of Compounds III-V, Compounds II-VI, and Compounds IV. Each semiconductor element defines, optionally with insulating portions partially covering said semiconductor element, at least one first surface (34) including contiguous facets angled relative to each other. The optoelectronic device includes quantum dots (60) at at least some of the seams between the facets. The quantum dots are predominantly made of a mixture of the first compound and an additional element and are suitable for emitting or receiving a first electromagnetic radiation at a first wavelength.
