Physical and electrical characterizations of low n-doped MOCVD GaN-on-sapphire layers for power electronics applications

Ndembi Ignoumba-Ignoumba, Camille Sonneville, Adrien Bidaud, Pierre Brosselard, Eric Frayssinet, Florian Bartoli, Yvon Cordier, Farid Medjdoub, Dominique Planson, Cyril Buttay

This work presents physical and electrical characterizations of low n-doped MOCVD GaN-on-sapphire layers and associated quasi-vertical Schottky Barrier Diodes (SBDs). Samples GaN drift layers have globally a similar quality as examined by XRD, AFM Raman spectroscopy, C-V measurements and I-V...

Thermoelastic properties of polycrystalline strontium titanium silicate Sr₂TiSi₂O₈ synthesized via the reactive sintering method

Oussama Zwein, Maurice Gonon, Sandra Abdelouhab, Isabella Mastroianni, Marc Duquennoy

The aim of the work presented in this paper is to investigate the thermoelastic properties of polycrystalline Sr-fresnoite Sr2TiSi2O8 (STS). On that purpose, Sr2TiSi2O8 samples were synthesized by solid state reactive sintering from SrCO3, TiO2 and SiO2 powders. The thermal expansion behaviour of...

Patterning and micromanipulation of miscible fluids using vortex-based single-beam acoustic tweezers

Samir Almohamad, Gustav Modler, Ravinder Chutani, Udita Ghosh, Sarah Cleve, Henrik Bruus, Michael Baudoin

Vortex-based single-beam tweezers have the ability to precisely and selectively move a wide range of objects, including particles, bubbles, droplets, and cells with sizes ranging from the millimeter to micrometer scale. In 2017, Karlsen and Bruus [Phys. Rev. Appl. 7, 034017 (2017)] theoretically...

Theoretical Framework for Semitransparent Organic Photovoltaics: Bridging Material Design with Optical Engineering

Baozhong Deng, Zhouyi Lu, Kaiwen Zheng, Bin Wei, Gaëtan Lévêque, Bruno Grandidier, Jianhua Zhang, Tao Xu

Semitransparent organic photovoltaics (ST‐OPVs) hold great promise for building‐integrated applications but encounter a critical trade‐off between power conversion efficiency (PCE) and visible transparency. This work addresses this challenge by introducing a novel theoretical framework that...

In Vitro Evaluation of Antibacterial Properties of NIR-Light Responsive Alginate Hydrogels Embedding Polydopamine Nanoparticles

Sarah Defrançois, Alexandre Barras, Mickaël Maton, Patrice Woisel, Feng Hildebrand, Nicolas Blanchemain, Rabah Boukherroub, Joël Lyskawa

acterial infections are one of the most serious health problems worldwide and represent a significant threat to humans. In this article, we designed an injectable alginate-based hydrogel embedding polydopamine nanoparticles (nPDA) and applied it as a (nano)phototherapeutic agent and nanocarrier for...

Silicate–sulfide interaction within quenched melts of space weathered Ryugu grains

Sylvain Laforet, Hugues Leroux, Corentin Le Guillou, Maya Marinova, Adrien Neri, Adrien Teurtrie, Francisco de la Peña, Damien Jacob, Alexandre Fadel, David Troadec

The first few microns of the surface of airless bodies are subject to severe changes due to the harsh environment of space, known as space weathering. The Hayabusa2 sample return mission from the asteroid Ryugu provides the first opportunity to study these effects on a carbonaceous and hydrated...

Topology optimization of phoxonic crystals for maximizing dual bandgaps using GA-SIMP method

Bin Li, S S Nanthakumar, Yan Pennec, Bahram Djafari-Rouhani, Xiaoying Zhuang

Phoxonic crystals are photonic-phononic or optomechanical periodic structures that simultaneously exhibit dual bandgaps. This allows for the confinement of both optical and elastic waves in cavities and waveguides, providing a powerful platform for novel optomechanical devices and systems. The...
