Electrical properties of light-addressed sub-µm electrodes fabricated by use of nanostencil-technology

Jürgen Brugger

A wide range of applications in neurotechnological research rely on planar microelectrode arrays (MEA) but the disadvantage of these systems is the low density of electrodes caused by the problem of wiring a great number of electrodes. In turn this results ...

Electrochemical oxidation of para-chlorophenol on Ti/SnO2-PbO2 electrodes: introduction of a parameter for the estimation of their efficiency

Christos Comninellis

The electrocombustion technique has recently been proposed to oxidize nonbiodegradable org. pollutants such as chlorophenol. The authors considered two different types of electrode material: boron doped diamond (BDD) and lead dioxide electrodeposited on Ti ...

Stress and piezoelectric properties of aluminum nitride thin films deposited onto metal electrodes by pulsed direct current reactive sputtering

Paul Muralt

Polycrystalline aluminum nitride thin films were deposited onto platinum, aluminum, and titanium electrodes by reactive magnetron sputtering in the pulsed direct current mode. The films exhibited all a columnar microstructure and a c-axis texture. The buil ...

Electrochemical synthesis of inorganic and organic compounds with Boron-Doped diamond electrodes

Christos Comninellis, Pierre-Alain Michaud

The Boron-Doped Diamond (BDD) electrode is a new electrode material with high stability, even at high anodic potential. Furthermore BDD is not prone to fouling. Due to these properties, BDD can provide new opportunities in electrochem. synthesis of org. an ...

Constant-current study of dielectric breakdown of Pb(Zr,Ti)O-3 ferroelectric film capacitors

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Serguei Okhonin

This paper addresses the problem of time-dependent dielectric breakdown of Pb(Zr,Ti)O-3 (PZT) thin films. It is shown by using constant-current breakdown measurements, that for PZT film capacitors with Pt and SrRuO3 (SRO) electrodes the breakdown onset is ...

Mechanistic studies of oxygen reduction at La0.6Ca0.4CoO3-activated carbon electrodes in a channel flow cell

Christos Comninellis, Stefan Müller

The mechanism of the oxygen redn. reaction (orr) was studied in alk. media at La0.6Ca0.4CoO3-activated carbon electrodes in a channel flow cell (CFC). The electrodes were made by depositing a mixt. of the perovskite (La0.6Ca0.4CoO3) powder as the catalyst, ...
