High quality drift layer thickness scaling in vertical GaN-on-Silicon PIN diodes

Youssef Hamdaoui, Idriss Abid, Sondre Michler, Katir Ziouche, F Medjdoub

We report on high drift layer quality in vertical PIN diodes grown on silicon substrate combining low Ron = 0.35 mΩ.cm², and high critical electric field of 1.82 MV/cm. The impact of the drift region thickness on the device performances shows an excellent breakdown scaling with 640 V / 820 V for 3....

A Very Low Power 12 bit 64-MS/s 2 step SAR Assisted Bidirectional Digital Slope ADC

Jean-Baptiste Casanova, Danika Perrin, Sandrine Nicolas, Andreas Kaiser

This paper presents a novel architecture of a SAR assisted 2 step ADC where the SAR residue is quantized with a bidirectional digital slope time-based converter. The bidirectional slope halves the conversion time of the second stage. Furthermore, the redundancy requirements in the second stage are...

CPW-Fed MIMO Smartphone Antenna Array with Radiation/Polarization Diversity for 5G Applications

Naser Ojaroudi Parchin, Mohammad Alibakhshikenari, Chan Hwang See, Iyad Dayoub, Raed Abd-Alhameed

This paper represents a new MIMO antenna design with compact diversity resonators for future smartphone applications. Four pairs of diversity monopoles with CPW feeding have been deployed at the mainboard’s corners to create an 8×8 MIMO configuration. The array designed takes up a comparatively...

A Neural Network to Decipher Organic Electrochemical Transistors’ Multivariate Responses for Cation Recognition

Sébastien Pecqueur, Dominique Vuillaume, Željko Crljen, Ivor Lončarić, Vinko Zlatić

Extracting relevant data from real-world experiments is often challenging with intrinsic materials and device property dispersion, such as in organic electronics. However, multivariate data analysis can often be a mean to circumvent this and to extract more information when larger datasets are used...

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...

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...
