Atomic switch : synaptic functionalities and integration strategies

Selina La Barbera, David Guérin, Dominique Vuillaume, F. Alibart

In recent years, research in the field of neuro-inspired computing has generated a lot of interest and seems to be a promising candidate to complement and to provide enhanced performances and new functionalities to the existing CMOS/Von Neumann processor, such as image recognition or datas…

Influence of processing gases on the properties of cold atmospheric plasma SiOxCy coatings

H. Hamze, Maude Jimenez, D. Deresmes, Arnaud Beaurain, Nicolas Nuns, Michel Traisnel

Thin layers of SiOxCy (y = 4−x and 3 ≤ x ≤ 4) were applied using a cold atmospheric plasma torch on glass substrates. The aim was to investigate using Atomic Force Microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (Tof-Sims) the influence of…

1900 V, 1.6 mΩ cm2 AlN/GaN-on-Si power devices realized by local substrate removal

Nicolas Herbecq, Isabelle Roch-Jeune, Nathalie Rolland, Domenica Visalli, Joff Derluyn, Stefan Degroote, Marianne Germain, F Medjdoub

We demonstrate a high-voltage low on-resistance AlN/GaN/AlGaN double heterostructure grown by metal-organic chemical vapor deposition on a silicon (111) substrate using a total buffer thickness of less than 2 μm. A fully scalable local substrate removal technique was developed to dramatically…

From semiconductor nanocrystals to artificial graphene and topological insulator

Efterpi Kalesaki, Christophe Delerue, Cristiane Morais Smith, Wouter Beugeling, Guy Allan, Daniel Vanmaekelbergh

Recent advancements in colloidal chemistry indicate that two-dimensional single-crystalline sheets of semiconductors forming a honeycomb lattice can be synthesized from semiconductor nanocrystals [1]. We perform atomistic tight-binding calculations of the band structure of CdSe sheets with such a…

Inkjet coplanar square monopole on flexible substrate for 60-GHz applications

Aimeric Bisognin, Julien Thielleux, Wei Wei, Diane Titz, Fabien Ferrero, Patrice Brachat, Gilles Jacquemod, Henri Happy, Cyril Luxey

In this letter, the design, fabrication, and measurement of a 60-GHz printed antenna with inkjet technology over a flexible substrate is presented. The antenna is a coplanar square monopole with omnidirectional radiation characteristics. We especially measured a 68% total efficiency and a maximum…

Modeling and simulation of AlxGayIn1-x-yAs/InP quaternary structure for photovoltaic

Abdelkader Aissat, M. El Bey, Rachid Bestam, Jean-Pierre Vilcot

In this work, we have studied solar cells based on AlGaInAs/InP quaternary structure to describe the behavior of electronics components. To this end, we have developed a simulation program to study the gallium Ga and aluminum Al concentrations effect on respectively the lattice mismatch, the band…

Guided wave in multilayered piezoelectric-piezomagnetic bars with rectangular cross-sections

J.G. Yu, Jean-Etienne Lefebvre, C. Zhang

For the purpose of design and optimization of multilayered piezoelectric-piezomagnetic material (PPC) transducers, wave propagation in these structures has received much attention in past ten years. But the research objects of previous works are only for semi-infinite structures and one-dimensional…
