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…

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…
