Abstract: An optoelectronic device including three-dimensional semiconductor elements 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 including contiguous facets angled relative to each other. The optoelectronic device includes quantum dots 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.

Abstract: A method for making patterns on the surface of a substrate by graphoepitaxy, includes depositing a layer of resin on the surface of the substrate; making patterns in the resin on the surface of a substrate; curing the patterns in the resin by producing a layer of amorphous carbon on the surface of the patterns in the resin; depositing a layer of statistical copolymer after curing the patterns in the resin; grafting the layer of statistical copolymer onto the patterns in the resin by annealing; and depositing a layer of a block copolymer into the spaces defined by the patterns in the resin after curing the patterns and the grafting of the layer of statistical copolymer.

Abstract: A process for moving a particle using a device, the device including a substrate, a wave guide and a grating formed on the wave guide. The process includes injecting light with wavelength ? into the wave guide, and diffracting the light transmitted through the guide to a medium with an index nsuper in which the particle is located, particle movement forces being generated by the diffraction of light from the grating.

Abstract: A method for separation of particles with different sizes. The method introduces radiation in a waveguide, coupled to a second guide in a coupling area, the radiation entraining all particles towards the coupling area, and separates the particles as they pass into the coupling area.
