Sputtered silicon carbide thin films as protective coating for MEMS applications

There is a need for chemically resistant coatings that protect the exposed surface of microfluidics components. Pinhole free films with low stress and a good uniformity on flat and inclined surfaces are required. In this study, amorphous silicon carbide (S ...

Preparation of peroxodisulfuric acid using boron-doped diamond thin film electrodes

Christos Comninellis, Pierre-Alain Michaud

The anodic oxidn. of H2SO4 to H2S2O8 was investigated on B-doped synthetic diamond electrodes obtained by hot filament chem. vapor deposition. High current efficiency for H2S2O8 formation can be achieved in concd. H2SO4 (7.5 mol dm-3) and using high curren ...

High-aspect-ratio, ultrathick, negative-tone near-UV photoresist and its applications for MEMS

Jürgen Brugger, Philippe Renaud, Peter Vettiger

Detailed investigations of the limits of a new negative-tone near-UV resist (IBM SU-8) have been performed. SU-8 is an epoxy-based resist designed specifically for ultrathick, high-aspect-ratio MEMS-type applications. We have demonstrated that with single- ...

CVD diamond probes for nanotechnology

Philippe Buffat

Diamond tips are attractive tools for nanoscience because of their hardness and, when doped chemical vapor deposited (CVD) diamond is used, their electrical conductivity. In this article, devices based on CVD diamond coated silicon tips and molded diamond ...

Fabrication of an anode with enhanced durability

Christos Comninellis

A dimensionally stable anode with enhanced durability for use in electrochem. processes (e.g. those involving evolution of Cl2 or O2) is described. The anode consists of a substrate of >=1 metals or metal oxides provided with an outer Ta surface coated wit ...

Controlling and tuning strong optical field gradients at a local probe microscope tip apex

Olivier Martin

We show that strong optical field gradients can be created at the tip apex of a local probe microscope illuminated by an external light source. We demonstrate that these confined fields can be easily, precisely and continuously tuned by changing the polari ...

Nucleation and growth of Cu/Ni(100): A variable temperature STM study

Klaus Kern, Harald Brune

A detailed study of the nucleation and growth of Cu on Ni(100) as a function of substrate temperature and deposition rate by variable temperature STM is reported. By the quantitative analysis of the saturation island density as a function of temperature an ...

Piezoelectric coatings for active optical fiber devices

Nava Setter, Hans Georg Limberger

A new class of active fiber devices based on piezoelectric coated optical fibers is currently being developed. The piezoelectric coating is used to produce acoustic waves within the optical fiber and these acoustic waves interfere with optical signals pass ...

Measurement of the optical depth at the third electron cyclotron harmonic in tore supra

Olivier Sauter, Timothy Goodman, Minh Quang Tran, Antoine Pochelon

The linear relativistic theory of electron cyclotron wave propagation predicts partial absorption of the extraordinary mode at the third electron cyclotron harmonic for typical parameters of present day tokamak plasmas. Since the waves are not totally damp ...

A method to measure the adhesion of thin glass coatings on polymer films

Yves Leterrier

A simple and reliable method to measure the adhesion of thin, hard coatings on polymer substrates is presented, based on the rupture mechanics of brittle films on ductile substrates. The regular fragmentation pattern of the coating obtained after straining ...
