Design and fabrication of nanofluidic devices by surfaces micromachining

Using surface micromachining technology, we fabricated nanofluidic devices with channels down to 10̂nm deep, 200̂nm wide and up to 8̂cm long. We demonstrated that different materials, such as silicon nitride, polysilicon and silicon dioxide, combined with ...

Novel full platinum nanoprobes suitable for biological SPM experiments

Jürgen Brugger, Johannes Steen

We present the fabrication and characterization of hybrid SPM probes with full platinum (Pt) cantilever and tip for biological SPM experiments. In recent years, SPM has shown its value in imaging and characterizing biological samples. Classic SPM sensors f ...

Préparation et caractérisation de nanoparticules bimétalliques (Pt-Au) sur un substrat en diamant dopé au bore

Bahaa El Roustom

Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...

Dielectric and infrared properties of ultrathin SiO2 layers on Si(100)

Alfredo Pasquarello

The occurrence of an ultrathin SiO2 oxide layer at the interface between silicon and high-k dielectrics in metal-oxide-semiconductor devices contributes to degrading the capacitance of the gate stack. In this work, we investigate the dielectric and infrare ...

Group iii nitride light-emitting devices having a polarization-doped region

Jean-François Carlin

A light-emitting device comprising a substrate-supported Group III nitride semiconductor region having a p-n junction region for injecting carriers into an optically active region, wherein the p-n junction region comprises an aluminum indium gallium nitrid ...

Metal-doped carbon aerogels as catalysts during ozonation processes in aqueous solutions

Urs von Gunten

The efficiency of Co(II)-, Mn(II)-, and Ti(IV)-doped carbon aerogels for the transformation of ozone into center dot OH radicals was investigated. The carbon aerogels had a markedly acid surface character (pH(PZC)congruent to 3-4) with very high surface ox ...

Corrugated membranes for improved pattern definition with micro/nanostencil lithography

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

We present a MEMS process for the fabrication of arbitrary (adaptable to specific aperture geometries) stabilization of silicon nitride membranes to be used as miniature shadow masks or (nano) stencils. Stabilization was realized by the fabrication of sili ...

SMALL AFM CANTILEVERS FOR BIOLOGICAL APPLICATION

Jürgen Brugger, Johannes Steen

Atomic Force Microscope is of special interest to biologists since it enables real time imaging and force measurements on biological tissue. To observe the biological process of interest in a reasonable time with high force sensitivity, high resonance freq ...

Boron-doped diamond (BDD)-supported Pt/Sn nanoparticles synthesized in microemulsion systems as electrocatalysts of ethanol oxidation

Christos Comninellis, György Foti, Guillaume Siné

Bimetallic Pt/Sn nanoparticles, synthesized by the microemulsion method, have been investigated once deposited on a boron-doped diamond (BDD) substrate electrode. Nanoparticles are in the nano-size domain and their effective composition corresponds to thei ...

Uniformity study in large-area showerhead reactors

Laurent Fabien Hubert Sansonnens, Raffaello Sobbia

Large area plasma-enhanced chemical vapor deposition of thin films such as silicon nitride or amorphous silicon is widely used for thin film transistor fabrication in the flat panel display industry. A numerical three-dimensional model to calculate the dep ...
