Elastic Metasurfaces for Deep and Robust Subwavelength Focusing and Imaging

Yabin Jin, Wan Wang, Abdelkrim Khelif, Bahram Djafari-Rouhani

Metasurfaces are planar metamaterials with a flat surface and a subwavelength thickness that are able to shape arbitrary wave fronts such as focusing or imaging. There is a broad interest in the literature about subwavelength focusing and imaging based on bulk metamaterials while the utilization of…

Nanoprobe study of the electric field driven insulator-to-metal transition in GaMo4S8

H. Koussir, Isabelle Lefebvre, Maxime Berthe, B. Grandidier, Pascale Diener, J. Tranchant, Benoit Corraze, Etienne Janod, Laurent Cario

The resistive switching observed under electric pulses in Mott materials has a high potential for micro and nanoelectronics. Here we report on the study of the resistive switching observed at the surface of single crystals of the canonical Mott semiconductor GaMo4S8. The study is made using a…

Evolution of localized surface plasmon resonance made of gold nanowire chain embedded in WS2multilayers

Z. Oumekloul, Y. Achaoui, A. Mir, Abdellatif Akjouj

Recently, the transition metal dichalcogenides (TMDs) have emerged as a new class of building blocks for engineering enhanced plasmonic sensors. This class of materials can be made with a low production cost and can be easily hybridized with metallic nanoparticles whereby desired molecules are…

Optimization of Reactive-Ion Etching (RIE) parameters to maximize the lateral etch rate of silicon using SF6/N2 gas mixture: An alternative to etching Si in MEMS with Au components

Munique Kazar Mendes, Cécile Ghouila-Houri, Serria Hammami, Thomas Arnoult, Philippe Pernod, Abdelkrim Talbi

In this work, the effects of the N2 addition to the SF6 plasma used in the isotropic silicon etching of Microelectromechanical systems (MEMS) with Au components are investigated. A four-variables Doehlert design was implemented for optimizing the etching parameters (power, pressure, gas flow rate,…

Radiation environment and doses on Mars at Oxia Planum and Mawrth Vallis: support for exploration at sites with high biosignature preservation potential

F. da Pieve, G. Gronoff, J. Guo, C. J. Mertens, L. Neary, B. Gu, N. E. Koval, J. Kohanoff, A. C. Vandaele, F. Cleri

The first human missions on MARS will likely involve several astrobiology‐driven science operations, at sites with high biosignature preservation potential. Here, we present a study of the radiation environment induced by Galactic Cosmic Rays and Solar Energetic Particles at OXIA PLANUM, landing…

Near-field scanning millimeter-wave microscope operating inside a scanning electron microscope: towards quantitative electrical nanocharacterization

Petr Polovodov, Didier Theron, Clément Lenoir, D. Deresmes, Sophie Eliet, Christophe Boyaval, Gilles Dambrine, Kamel Haddadi

The main objectives of this work are the development of fundamental extensions to the existing scanning microwave microscopy (SMM) technology to achieve quantitative complex impedance measurements at the nanoscale. We developed an SMM operating up to 67 GHz inside a scanning electron microscope…
