Enhanced tunability and temperature-dependent dielectric characteristics at microwaves of K0.5Na0.5NbO3 thin films epita...
...
K0.5Na0.5NbO3 thin films were deposited by pulsed laser deposition on (100)MgO substrates for microwave device applications. A fine epitaxial growth of pure perovskite phase was evidenced by X-ray diffraction. Dielectric characterizations were performed from 1 to 40 GHz using coplanar microwave devices printed on the 500 nm-thick K0.5Na0.5NbO3 thin...
Direct Non-Invasive Measuring Techniques ofNanometric Liquid Level Variations UsingExtrinsic Fiber Fabry–Perot Interfero...
This article investigates two different non-contact non-invasive solutions for measuring nanometric-order liquid-surface displacements with Extrinsic FiberFabry-Perot interferometers. They are investigated fordeveloping hydrostatic leveling sensor (HLS) systemstargeting the detection of very slowly-evolving movementsin geophysics and geotechnics. I...

Investigation of Oxygen penetration during UV Nanosecond Laser Annealing of Silicon at high energy densities
...
In this work, we present a comprehensive investigation of impurities contamination in silicon during UV Nanosecond Laser Annealing at high energy density. By investigating in detail the impact of the annealing ambient and of the surface preparation prior to UV-NLA (including the variation of the surface oxide thickness), we show that the observed o...

Special issue on Monolithic 3D: Technology, Design and Computing Systems Applications Perspectives
Scope and PurposeOver the last 50 years, Computing Systems have successfully surfed the Moore’s law wave. Today, we observe a clear stagnation in this miniaturization race while a new generation of applications (such as Artificial Intelligence) are producing unprecedented amounts of raw data. To overcome this major challenge, new technologies aimin...
Strain dependence of dissociative adsorption of H 2 O on epitaxially strained, out-of-plane polarized, BaTiO 3 (001) thi...
The strain dependence of the apparent activation energy of desorption of H 2 O on epitaxial, TiO 2-terminated, outof-plane polarized, BaTiO 3 (100) thin films has been investigated using X-ray diffraction, X-ray photoelectron spectroscopy and temperature-programmed desorption. The apparent activation energy of desorption increases significantly wit...
