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…

Negative effective mass density of acoustic metamaterial plate decorated with low frequency resonant pillars

Mourad Oudich, Bahram Djafari-Rouhani, Yan Pennec, M. Badreddine Assouar, Bernard Bonello

We investigate the elastic wave dispersion by a phononic metamaterial plate containing low frequency resonator stubs arranged periodically over the plate. We show that this system not only provides stop bands for wavelengths much larger than the periodicity but also displays negative behavior of…

Dielectric relaxation analysis of Pb(Zr_0.54,Ti_0.46)O₃ thin films: electric field dependence

Freddy Ponchel, N. Sama, Denis Remiens, T. Lasri

350 nm-thick Perovskite PbZr0.54Ti0.46O3 (PZT) thin films were deposited on Al2O3 substrates by sputtering with and without an additional 10-nm-thick TiOx buffer layer. X-ray diffraction patterns showed that in presence of TiOx buffer layer, PZT film was highly oriented along the (111) direction…

Enhanced efficiency by the effect of strain on the structure of a solar cell

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

This paper is expected at the study of Ga1-xInxP/GaAs based solar cell. The effects of indium concentration, lattice parameter mismatch and thickness of the SiO2 insulating layer on the characteristics and efficiency of the Ga1-xInxP/GaAs structure were investigated. We noticed that for higher…

Cross-talk artefacts in Kelvin probe force microscopy imaging : a comprehensive study

Sophie Barbet, Michka Popoff, Heinrich Diesinger, D. Deresmes, Didier Theron, Thierry Melin

We provide in this article a comprehensive study of the role of ac cross-talk effects in Kelvin Probe Force Microscopy (KPFM), and their consequences onto KPFM imaging. The dependence of KPFM signals upon internal parameters such as the cantilever excitation frequency and the projection angle of…

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…

Sub-THz characterisation of multi-walled carbon nanotube thin films using vector network analyser

S. Puthukodan, E. Dadrasnia, V.K.T. Vinod, H.K. Nguendon, H. Lamela, Guillaume Ducournau, Jean-Francois Lampin, F. Garet, J.L. Coutaz, D.M. Lee, S. Baik

A vector network analyser is used to study the electrical properties of multi-walled carbon nanotube (MWCNT) thin films deposited on a fused quartz substrate in the sub-terahertz (THz) frequency ranges of 220-325 GHz (WR3.4) and 325-500 GHz (WR2.2). The experiment is performed in free space. The…
