Coplanar liquid crystal reconfigurable phase-shifters

Fehim Sahbani, Nicolas Tentillier, Christian Legrand, Karine Blary, A. Gharsallah, A. Gharbi

A coplanar liquid crystal phase-shifter is presented and characterized in the frequency range of 5–40 GHz. The interest of this structure lies in the technological realization which is very simple. The phase-shift variation is of 0.2°/cm/GHz for an attenuation of 2.5 dB/cm at 40 GHz. These…

One port contour-mode ZnO piezoelectric MEMS resonator

Tadeusz Gryba, Julien Carlier, S.X. Wang, X.Z. Zhao, S. Guo, Jean-Etienne Lefebvre

This paper reports on design, fabrication and experimental testing of one port ZnO contour-mode resonant MEMS. The devices are fabricated from silicon wafers using a 4-mask process. The use of contour modes, whose frequencies are set by lithographically defined dimensions, permits the fabrication…

Magnonic circuits and crystals

Housni Al-Wahsh, Abdellatif Akjouj, Bahram Djafari-Rouhani, L. Dobrzynski

In the frame of the long-wavelength Heisenberg model, a simple magnonic mono-mode circuit is designed to obtain transmission stop (pass) bands where the propagation of spin waves is forbidden (allowed). This simple device is composed of an infinite one-dimensional monomode waveguide (the backbone)…

Strain relief at the GaSb/GaAs interface versus substrate surface treatment and AlSb interlayer thickness

Y. Wang, P. Ruterana, L. Desplanque, S. El Kazzi, X. Wallart

Using transmission electron microscopy we investigate the influence of AlSb monolayers and substrate surface preparation on the microstructure of GaSb grown on GaAs (001) by molecular beam epitaxy. The geometric phase analysis method is used to analyze the interface dislocation type and the…

Erbium silicide growth in the presence of residual oxygen

N. Reckinger, Xing Tang, S. Godey, Emmanuel Dubois, A. Laszcz, J. Ratajczak, Adriana Vlad, C.A. Dutu, J.P. Raskin

The chemical changes of Ti/Er/n-Si(100) stacks evaporated in high vacuum and grown ex situ by rapid thermal annealing were scrutinized. The emphasis was laid on the evolution with the annealing temperature of (i) the Er-Si solid-state reaction and (ii) the penetration of oxygen into Ti and its…
