A 250 MHz to 1.1 THz sub-mm wave on-wafer characterization of InP HEMT using a multiline Thru-Reflect-Line calibration kit

Rita Younes, Mohammed Samnouni, Sylvie Lepilliet, Guillaume Ducournau, Nicolas Wichmann, Sylvain Bollaert

Abstract In this paper, we report an on-wafer High-Electron-Mobility transistor characterization method over a large frequency band [250 MHz–1.1 THz]. The transistor’s coplanar accesses were optimized to enable high-frequency measurement of the devices up to 1.1 THz. The characterization method...

Do Micropower Sources Meet the Needs of the Internet of Things?

Grace Whang, Randy Chen, Jacky Yu, Christopher Choi, Patricia Mcneil, Jérémie Chaillou, Christophe Loyez, Christophe Lethien, Bruce Dunn

Abstract The rapid global adoption of the Internet of Things (IoT), combined with the ongoing trend toward device miniaturization, has marked the emergence of compact, connected technologies. However, as device dimensions continue to decrease, power sources remain a critical bottleneck. Micropower...

Strain Decoupling in Ge/Si via Selective Misfit-Network Etching.

Youcef A Bioud, Meriem Bouchilaoun, Waldemar Schreiber, Redouane Amrar, Gilles Patriarche, Ali Soltani, Stefan Janz

CMOS-compatible Ge/Si heterostructures enable high-performance electroabsorption modulators, photodetectors, photonic interconnects, and multijunction photovoltaics, yet their scalability is hindered by the 4.2% lattice and thermal mismatch that generates dense dislocations. Here, we report a...

On the origin and suppression of parasitic channel in AlN/GaN/AlGaN back barrier RF devices

L. Ben Hammou, F. Grandpierron, E. Carneiro, Katir Ziouche, Etienne Okada, F. Medjdoub

This work investigates the origin and physical location of a parasitic conduction path in GaN devices incorporating an AlGaN back barrier (BB) through a combined approach of calibrated Technology Computer-Aided Design (TCAD) simulations and experimental C–V and I–V measurements on Schottky diodes...

Temperature sensor based on topological edge states in one-dimensional photonic crystals with a superconductor cavity

Soukaina Sabsi, Fatima Zohra Harroui, Mohammed Elaouni, Ossama El Abouti, Tarik Mrabti, Madiha Amrani, Soufyane Khattou, Afaf Bouzidi, El Houssaine El Boudouti, Bahram Djafari-Rouhani

In this study, we investigate topological edge states (TES) arising at the interface of two distinct one-dimensional topological photonic crystals (1D-TPhCs) with a superconducting layer at the interface, designed for high-performance sensing. To investigate the optical properties and topological...

Development of a smart farming tool to monitor the degree of dew retting of flax stems

Ali Reda, Jean-Michel Mallet, Lionel Buchaillot, Steve Arscott

Flax fibres are a natural, sustainable product which have applications ranging from textiles to composite materials. A process known as 'retting' is required to facilitate the mechanical extraction of flax fibres from their associated stems. The goal of retting is to break down the...
