The correlation between skyrmion size, shape and device geometry

W. Al Saidi, R. Sbiaa, Nicolas Tiercelin

This study calculates the radius of the skyrmion for nanotracks with varying widths, exploring the effect of device geometry on the size of the skyrmion. While previous studies have evaluated the skyrmion radius for materials with different properties, less work has focused on the impact of device…

Mitigation of He permeation in microfabricated vapor cells with alumino-silicate glass and Al2O3 coatings

Clément Carlé, Shervin Keshavarzi, Andrei Mursa, Petri Karvinen, Ravinder Kumar Chutani, Sylwester Bargiel, Rémy Vicarini, Philippe Abbé, Moustafa Abdel Hafiz, Vincent Maurice, Rodolphe Boudot, Nicolas Passilly

We study helium permeation in micro-fabricated Cs vapor cells built with alumino-silicate glass (ASG) or borosilicate (BSG) windows, coated or not with Al2O3 layers. Gas permeation rate is derived from long-term measurements of the pressure-shifted clock hyperfine transition frequency in a coherent…

A multi-state memory device based on the Manipulation of a single skyrmion using spin-polarized current

W. Al Saidi, R. Sbiaa, Stan Laurel, Nicolas Tiercelin

Towards a multistate skyrmionic device, Firstly, the motion of a single skyrmion under spin-transfer-torque (STT) is studied in the conventional and constricted wire the study reveals the possibility to pin, depin and annihilate skyrmion. Later, a stepped nano-track with bottom and top confinements…

Quantifying and correcting tilt-related positioning errors in microcantilever-based microelectromechanical systems probes

Steve Arscott

The impact of tilt-related errors on the positioning of microcantilever-based microelectromechanical systems (MEMS) on-wafer electrical probes, having multiple contact pads, is quantified and investigated here. A tilt error associated with probe roll results in the probe contact pads not being…

Development of 3D organic polymer dendrites as neuromorphic device, Développement de dendrites polymères organiques en 3D comme dispositif neuromorphique

Kamila Janzakova

Neuromorphic technologies is a promising direction for development of more advanced and energy-efficient computing. They aim to replicate attractive brain features such as high computational efficiency at low power consumption on a software and hardware level. At the moment, brain-inspired software…, Les technologies neuromorphiques constituent une voie prometteuse pour le développement d'une informatique plus avancée et plus économe en énergie. Elles visent à reproduire les caractéristiques attrayantes du cerveau, telles qu'une grande efficacité de calcul et une faible consommation d…

Vibrotactile Thresholds on the Wrist for Vibrations Normal to the Skin

Quentin Consigny, Nathan Ouvrai, Arthur Paté, Claudia Fritz, Jean-Loïc Le Carrou

In order to facilitate the development of wrist-worn vibrotactile devices, detailed knowledge about how vibrations are perceived by the users is needed. In particular, perceptual thresholds in amplitude are really important. Thresholds have been measured in the literature for other areas of the…
