The effect of bottom electrode on the performance of thin film based capacitors in the gigahertz region

Capacitors in metal-insulator-metal structure have been fabricated with different bottom electrodes. It has been found that the observed losses are enormous at gigahertz frequencies unless due care is taken not only for the conductivity of the bottom elect ...

Degradation of asymmetrical Pt/SRO/PLZT/Pt capacitors: Role of Pt and oxide electrodes

Nava Setter, Alexander Tagantsev, Igor Stolichnov

Role of Pt and SRO electrodes in polarization fatigue of PLZT film ferroelectric capacitors is studied. We show that asymmetrical Pt/SRO/PLZT/Pt structure exhibits unusual dependence of the endurance of switching polarization on the driving ac electric fie ...

Discrimination between bulk and interface scenarios for the suppression of the switchable polarization (fatigue) in Pb(Zr,Ti)O-3 thin films capacitors with Pt electrodes

Nava Setter, Alexander Tagantsev, Enrico Colla

A simple and reliable method which allows one to distinguish between the two major microscopic scenarios for the suppression of the switching polarization (P-r(s)), i.e., pinning of ferroelectric domain walls (DWs) through the Pb(Zr,Ti)O-3 film (PZT) (bulk ...

Divertor target profiles and recycling studies in TCV single null lower standard discharges

Basil Duval, Yves Martin, Jean-Marc Moret, René Chavan, Xavier Llobet, Henri Weisen, Jonathan Bryan Lister, Richard Pitts, Roland Behn

A 'standard', single null lower diverted discharge has been developed to enable continuous monitoring of the first wall conditions and to characterise the effectiveness and influence of wall conditioning in the TCV tokamak. Measurements over a period encom ...

Fast electrochromic switching with nanocrystalline oxide semiconductor films

Michael Graetzel, Nikolaos Vlachopoulos, Ulf Anders Hagfeldt

Forward biasing of transparent nanocryst. TiO2 (anatase) films in lithium ion-contg. org. electrolytes leads to rapid and reversible coloration due to electron accumulation and Li+ intercalation in the anatase lattice. Absorption of >90% light throughout t ...

Lorentz Force Infiltration Of Fibrous Preforms

Andreas Mortensen

A new process for the production of metal matrix composites, whereby molten metal is forced into the interstices of a fibrous preform using electromagnetic body forces, is presented. These forces are created by subjecting the molten matrix to a concentrate ...

Characterization of dimensionally stable anodes DSA-type oxygen evolving electrodes. Choice of base metal

Christos Comninellis

In the search for a good DSA-type O2-evolving electrode, the influence of the base metal (titanium, tantalum, zirconium, niobium and some of their alloys) on the performance of IrO2-Ta2O5 coated electrodes, was investigated. The thermal behavior and oxygen ...

Results of computer simulation of subsynchronous resonance of synchronous generators

Basile Kawkabani, Jean Chatelain

Shaft systems of large turbine-generators can be subjected to high torsional stresses due to subsynchronous resonance especially in networks with capacitor- compensated lines. A second benchmark model for computer simulation of this phenomena has been prop ...
