Rigorous extraction tunability of Si-integrated Ba0.3Sr0.7TiO3 thin film up to 60 GHz

Freddy Ponchel, Jean-François Legier, Caroline Soyer, Denis Remiens, Jean Midy, Tuami Lasri, Guillaume Guéguan

400-nm-thick Ba0.3Sr0.7TiO3 thin films are deposited on high resistivity silicon by in situ radio frequency magnetron sputtering. Coplanar waveguides with 1µm slot width are designed, with accurate knowledge frequency losses behavior, to determine ferroelectric thin-films properties up to 60 GHz....

Interface depolarization field as common denominator of fatigue and size effect in Pb(Zr0.54Ti0.46)O3 ferroelectric thin film capacitors

Rachid Bouregba, N. Sama, Caroline Soyer, Gilles Poullain, Denis Remiens

Dielectric, hysteresis and fatigue measurements are performed on Pb(Zr0.54Ti0.46)O3 (PZT) thin film capacitors with different thicknesses and different electrode configurations, using platinum and LaNiO3 conducting oxide. The data are compared with those collected in a previous work devoted to...

Caractérisation Ultrasonore de Plaques PoroViscoElastiques à l'Aide des Termes de Transition

Serge Derible, Pierre Campistron, Georges Freiha, Hervé Franklin, Bertrand Nongaillard

Nous présentons les résultats de la mesure des termes de transition, issus des coefficients de réflexion et de transmission d'une onde acoustique par et à travers des plaques poreuses. Ces termes permettent de séparer les contributions symétriques et anti symétriques des vibrations des...

Two-dimensional Legendre polynomial modeling of composite bulk acoustic wave resonators

A. Raherison, Jean-Etienne Lefebvre, F.E. Ratolojanahary, L. Elmaimouni, Tadeusz Gryba

A bidimensional analysis of 6 mm hexagonal resonators is described using a double orthonormal basis set for the expansion of field quantities. The analysis takes into account the electrical voltage source and by means of a unique formalism along with a single calculation restitutes all the types of...

Transport through open quantum dots : making semiclassics quantitative

I. Brezinova, L. Wirtz, S. Rotter, C. Stampfer, J. Burgdorfer

We investigate electron transport through clean open quantum dots (“quantum billiards”). We present a semiclassical theory that allows to accurately reproduce quantum transport calculations. Quantitative agreement is reached for individual energy and magnetic field dependent elements of the...

Development of Time-resolved UV Micro-Raman Spectroscopy to measure temperature in AlGaN/GaN HEMTs

Ophélie Lancry, Emmanuelle Pichonat, Julien Réhault, Myriam Moreau, Raphaël Aubry, Christophe Gaquière

We report on the development of Time-resolved Ultraviolet Micro-Raman Scattering to measure transient self-heating effects in semiconductor devices. Temperature measurements are performed on AlGaN/GaN High-electron-mobility transistors (HEMTs) grown on SiC substrate. Ultraviolet excitation probes...
