چکیده

We report on two gas phase nanoparticle integration processes to assemble nanomaterials onto desired areas on a substrate. We expect these processes to work with any material that can be charged. The processes offer self-aligned integration and could be applied to any nanomaterial device requiring site specific assembly. The Coulomb force process directs the assembly of nanoparticles onto charged surface areas with sub-100 nm resolution. The charging is accomplished using flexible nanostructured electrodes. Gas phase assembly systems are used to direct and monitor the assembly of nanoparticles onto the charge patterns with a lateral resolution of 50 nm. The second concept makes use of fringing fields. The fringing fields directed the assembly of nanoparticles into openings. The fringing fields can be confined to sub 50 nm sized areas and exceed 1 MV/m, acting as nanolenses. Gas phase assembly systems have been used to deposit silicon, germanium, metallic, and organic nanoparticles.

Gas Phase Nanowire Integration Process PI : Heiko

We report on a gas phase process to synthesize and integrate seed particles and inorganic nanowires with control over location, diameter, length, and geometrical orientation. The process flow begins with the gas phase synthesis and size selection of nanoparticle seeds. The seed particles are deposited onto addressable locations on a substrate by Coulomb force and fringing field directed assembl...

Haloing in bimodal magnetic colloids: the role of field induced phase separation C.Magnet, P.Kuzhir, G.Bossis, A.Meunier, L.Suloeva and A.Zubarev

If a suspension of magnetic micron-sized and nano-sized particles is subjected to a homogeneous magnetic field, the nanoparticles are attracted to the microparticles and form thick anisotropic halos (clouds) around them. Such clouds can hinder approach of microparticles and result in effective repulsion between them [Lopez-Lopez et al. Soft Matter, 6, 4346 (2010)]. In this paper, we present det...
