In-situ electrical addressing of one-dimensional gold nanoparticle assemblies

Heinrich Hofmann, Frédéric Juillerat

Substrates with 1-dimensional nanosize grooves were prepared using extreme-ultraviolet interference lithography (EUV-IL), wherein gold nanoparticles were self-assembled to form 1-dimensional structures. To measure the electrical properties of gold nanopart ...

Self-assembled nanostructures prepared by colloidal chemistry

Frédéric Juillerat

The use of nanomaterials has been shown to be promising in potential applications such as magnetic storage devices, nano-optical devices and sensors, amongst others. Such applications require the disposition of nanoparticles, of a wide variety of materials ...

Formation and Drying of Colloidal Crystals Using Nanosized Silica Particles

Paul Bowen, Heinrich Hofmann, Frédéric Juillerat

Much interest has been generated in the fabrication of colloidal crystals from suspensions because of the promise of photonic band gap applications. However, since the case of small, nonsedimenting colloidal particles indeed remains rather rarely treated, ...

Fabrication of large-area ordered arrays of nanoparticles on patterned substrates

Paul Bowen, Heinrich Hofmann, Frédéric Juillerat

Many potential applications in nanotechnology require virtually defect-free arrays of nanometre-scale particles over large areas. Guided self-assembly of colloidal particles on patterned templates has been shown to produce ordered arrays of colloidal parti ...

Aggregation and Charging of Colloidal Silica Particles: Effect of Particle Size

Paul Bowen, Frédéric Juillerat, Michal Borkovec

We studied systematically aqueous suspensions of amorphous well-characterized silica particles by potentiometric titration, electrophoretic mobility, and time-resolved light scattering. Their charging behavior and aggregation rate constants were measured a ...
