Physical Insights of thin AlGaN Back Barrier for millimeter-wave high voltage AlN/GaN on SiC HEMTs

Ajay Shanbhag, Francois Grandpierron, Kathia Harrouche, Farid Medjdoub

In this work, physical mechanisms underlying carbon-doped buffer combined with an AlGaN back-barrier layer are investigated in state-of-the-art millimeter-wave AlN/GaN transistors. We have fabricated devices with and without the insertion of a thin AlGaN back-barrier layer with reduced carbon...

Capillary-driven horseshoe vortex forming around a micro-pillar

K. Ozawa, H. Nakamura, K. Shimamura, G.F. Dietze, H.N. Yoshikawa, Farzam Zoueshtiagh, K. Kurose, L. Mu, I. Ueno

Hypothesis: Horseshoe vortices are known to emerge around large-scale obstacles, such as bridge pillars, due to an inertia-driven adverse pressure gradient forming on the upstream-side of the obstacle. We contend that a similar flow structure can arise in thin-film Stokes flow around micro-...

All-Solid-State Interdigitated Micro-Supercapacitors Based on Porous Gold Electrodes

Aymeric Pastre, Alexandre Boé, Nathalie Rolland, Rémy Bernard

Recent developments in embedded electronics require the development of micro sources of energy. In this paper, the fabrication of an on-chip interdigitated all-solid-state supercapacitor, using porous gold electrodes and a PVA/KOH quasisolid electrolyte, is demonstrated. The fabrication of the...

Mid-wave Infrared sensitized InGaAs using Intraband Transition in Doped Colloidal II-VI Nanocrystals

Adrien Khalili, Mariarosa Cavallo, Tung Huu Dang, Corentin Dabard, Huichen Zhang, Erwan Bossavit, Claire Abadie, Yoann Prado, Xiang Zhen Xu, Sandrine Ithurria, Grégory Vincent, Christophe Coinon, Ludovic Desplanque, Emmanuel Lhuillier

Narrow bandgap nanocrystals (NCs) are now used as infrared light absorbers, making them competitors to epitaxially grown semiconductors. However, these two types of material could benefit from one another. While bulk materials are more effective in transporting carriers and give a high degree of...

Bound States in the Continuum and Induced Resonances in a Simple Plasmonic Waveguide with Sensing Application

Yamina Rezzouk, Soufyane Khattou, Madiha Amrani, Adnane Noual, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

A Friedrich–Wintgen bound state in the continuum (FW-BIC) is of particular interest in the field of wave physics phenomena. It is induced via the destructive interference of two modes that belong to the same cavity. In this work, we analytically and numerically show the existence of FW-BIC in a T-...

La spectroscopie térahertz: électrons et vibrations

Sarah Houver, Sophie Eliet Eliet-Barois, Pascale Roy, Romain Peretti

Les progrès technologiques ces dernières décennies ont fait croître de façon exponentielle l’utilisation de la spectroscopie TéraHertz. Cette gamme spectrale (1 THz = 1012 Hz) permet de sonder et caractériser les phénomènes physiques à basse énergie, où de nombreux processus élémentaires dans la...

Quasi van der Waals Epitaxy of Rhombohedral-Stacked Bilayer WSe₂ on GaP(111) Heterostructure

Aymen Mahmoudi, Meryem Bouaziz, Niels Chapuis, Geoffroy Kremer, Julien Chaste, Davide Romanin, Marco Pala, François Bertran, Patrick Le Fèvre, Iann C Gerber, Gilles Patriarche, Fabrice Oehler, Xavier Wallart, Abdelkarim Ouerghi

The growth of bilayers of two-dimensional (2D) materials on conventional 3D semiconductors results in 2D/3D hybrid heterostructures, which can provide additional advantages over more established 3D semiconductors while retaining some specificities of 2D materials. Understanding and exploiting these...
