Representative Behaviour and Adaptation of Office Occupants in Building Simulation
Darren Robinson, Frédéric Haldi
During the warm summer of 2006 a comprehensive longitudinal field survey of the adaptive actions of occupants, their thermal satisfaction and the coincident environmental conditions was conducted in eight Swiss offices. Based on analysis of these results w ...
EPFL2007Modeling of periodic distributed MEMS and application to the design of variable true-time delay lines
Anja Skrivervik, Pedro Crespo Valero, Julien Perruisseau-Carrier, Raphaël Fritschi
This paper presents the modeling and design methods of true-time distributed microelectromechanical systems transmission lines (DMTLs) making use of periodic structure theory. New contributions to the analysis and reduction of the microelectromechanical sy ...
2006Characterization of deep levels in n-GaN by combined capacitance transient techniques
Jean-François Carlin, Marc Ilegems, Marcel Py
Deep centers in undoped n-GaN grown by Hydride Vapor Phase Epitaxy were characterized by Deep Level Transient Spectroscopy (DLTS), revealing four known levels with activation energies in the range 0.17-0.94 eV. Deeper levels in the bandgap were observed by ...

Jean-Jacques Simond, André Hodder, Alexander Schwery
The present paper investigates the complete regulation strategy for a large double-fed asynchronous motor-generator equipped with a 3-level VSI cascade for applications mainly in the field of pumped storage plant. For the present application, the specific ...
2004Mechanical stress effect on imprint behavior of integrated ferroelectric capacitors
Stress-induced changes in the imprint and switching behavior of (111)-oriented Pb(Zr,Ti)O-3 (PZT)-based capacitors have been studied using piezoresponse force microscopy. Visualization of polarization distribution and d(33)-loop measurements in individual ...
2003Unusual size effect on the polarization patterns in micron-size Pb(Zr,Ti)O-3 film capacitors
Nava Setter, Alexander Tagantsev, Igor Stolichnov, Enrico Colla
Direct observation of polarization distribution at nanoscale by scanning force microscopy across partially etched Pb(Zr,Ti)O-3 film ferroelectric capacitors with size 2x3 mum and preferential orientation (111) has revealed an anomalous polarization pattern ...
2002Evidence for forward domain growth being rate-limiting step in polarization switching in < 111 >-oriented-Pb(Zr0.45Ti0.55)O-3 thin-film capacitors
We studied polarization switching of 295 nm thick -oriented-Pb(Zr0.45Ti0.55)O-3 (PZT) thin-film capacitors through a polarization hysteresis loop and piezoelectric force microscopy (PFM) on top of the Pt electrode. Positive voltage pulses of 450 kV/cm ...

Nava Setter, Dragan Damjanovic, Marco Cantoni
Thin films of neodymium-modified bismuth titanate Bi3.44Nd0.56Ti3O12 (BNT) were grown on Pt/TiO2/SiO2/Si substrates using chemical solution deposition method. The capacitors made by applying top Au electrodes on BNT films showed significantly improved valu ...
2002Dielectric breakdown in (Pb,La)(Zr,Ti)O-3 ferroelectric thin films with Pt and oxide electrodes
Nava Setter, Alexander Tagantsev, Igor Stolichnov, Serguei Okhonin
Dielectric breakdown of (Pb,La)(Zr,Ti)O-3(PLZT) film capacitors with Pt and SrRuO3 electrodes, in its initial or virgin state and after voltage cycling that causes polarization fatigue, is studied by constant-current measurements. It is shown that for diff ...
2000The 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 ...
