Three-paths microwave interferometric system based on a six-port technique

Kamel Haddadi, T. Lasri

This paper presents a new type of six-port instrument to meet the specific needs of electrical characterization tools for impedances clearly different than the standard 50Ω reference impedance. A method is developed for the precise adjustment of the reference impedance of the measurement system to...

Modelling Of Supramolecular Network Deposited On A Semiconductor Surface

Guillaume Copie, Christophe Krzeminski, Fabrizio Cleri, Younes Makoudi, B. Grandidier, Frédéric Cherioux, Frank Palmino

We investigated the self-assembly mechanisms and electronic properties of highly- symmetric organic molecules based on a substituted 1,2,5-tri(4-phenyl)benzene core[1], deposited on a passivated boron-doped Si(111)-√3x√3 R30° surface, by using ab-initio calculations, empirical molecular dynamics...

Relationship between ultrasonic Rayleigh wave propagation and capillary porosity in cement paste with variable water content

Fethi Soltani, Marc Goueygou, Zoubeir Lafhaj, Bogdan Piwakowski

The relationship between Rayleigh wave velocity at ultrasonic frequencies and capillary porosity is investigated in dry and water saturated cement paste. Capillary porosity is varied by changing the water/cement (w/c) ratio. Water saturation is set at four levels - 100, 70, 30 and 0% - by drying...

Thermal conductivity from approach-to-equilibrium molecular dynamics

E. Lampin, Pier Luca Palla, P.A. Francioso, F. Cleri

We use molecular dynamics simulations to study the thermal transport properties of a range of poor to good thermal conductors by a method in which two portions are delimited and heated at two different temperatures before the approach-to-equilibrium in the whole structure is monitored. The...

Effect of residual stress on energy storage property in PbZrO3 antiferroelectric thin films with different orientations

J. Ge, Denis Remiens, J. Costecalde, Y. Chen, X.L. Dong, G.S. Wang

The effect of residual stress on energy storage property was investigated for a series of PbZrO3 thin films on SrTiO3 and Si substrates. Compressive or tensile residual stress influences the critical electric field EA for the ferroelectric-to-antiferroelectric phase transition, thus for films with...
