Highly Conductive Tungsten Suboxide Nanotubes

Cécile Huez, Maxime Berthe, Florence Volatron, Jean-Michel Guigner, Dalil Brouri, Lise-Marie Chamoreau, Benoît Baptiste, Dominique Vuillaume, Anna Proust

We demonstrate a high electron conductivity (> 10^2 S/cm and up to 10^3 S/cm) of tungsten suboxide W18O(52.4-52.9)(or equivalently WO(2.91-2.94)) nanotubes (2 to 3 nm in diameter, ca. micrometer long). The conductivity is measured in the temperature range 120 to 300K by a four probe scanning…

Highly Si‐doped GaN regrown by MOVPE for ohmic contact applied to quaternary barrier based HEMT

Charles Pitaval, Cédric Lacam, N. Defrance, Christophe Gaquière, Nicolas Michel, Olivier Parillaud, Sylvain Delage

The quaternary barrier InAlGaN is suitable for GaN HEMT power microwave applications. High doping of semiconductor under the drain and source is a known suitable solution to achieve low ohmic contact resistance. However, InAlGaN quaternary alloys require low thermal budget to avoid indium…

An efficient cobalt-nickel phosphate positive electrode for high-performance hybrid microsupercapacitors

Min Li, Chen Jia, Danyu Zhang, Yunyun Luo, Yintao Ma, Guoxi Luo, Libo Zhao, Lu Wang, Zhikang Li, Qijing Lin, Ping Yang, Nan Zhu, Rabah Boukherroub, Zhuangde Jiang

Flexible energy storage devices play significant role in wearable and portable electronics. Herein, a cobalt-nickel phosphate (CoNiP2O7) composite was synthesized on conductive carbon nanotubes (CNTs) substrate by facile one-step electrochemical deposition method, forming a binder-free CoNiP2O7@…

Charge-Dependent Flexural Rigidity of a Conductive Polymer Laminate for Bioinspired Non-thermal Compliance Modulation

Yauheni Sarokin, Vadim Becquer, Eric Cattan, Alvo Aabloo, Indrek Must

Material-level stiffness modulation allows for the creation of controllable energy-dissipating structures for auxiliary and training exoskeletons and the manipulation of delicate objects and tissues. These use cases require simple control systems and disfavour thermally driven solutions. Many…

Sensor-Location-Specific Joint Acquisition of Peripheral Artery Bioimpedance and Photoplethysmogram for Wearable Applications

Margus Metshein, Anar Abdullayev, Antoine Gautier, Benoit Larras, Antoine Frappe, Barry Cardiff, Paul Annus, Raul Land, Olev Märtens

Background: Cardiovascular diseases (CVDs), being the culprit for one-third of deaths globally, constitute a challenge for biomedical instrumentation development, especially for early disease detection. Pulsating arterial blood flow, providing access to cardiac-related parameters, involves the…

Solid-Electrolyte-Free O3-LixTiS2 Cathode for High-Energy-Density All-Solid-State Lithium-Metal Batteries

Benjamin Hennequart, Michael Deschamps, Ronan Chometon, Bernhard Leube, Romain Dugas, Elisa Quemin, Pierre-Etienne Cabelguen, Christophe Lethien, Jean-Marie Tarascon

Composites made of high-capacity and high-potential LiNixMnyCo1–x–yO2 (NMC) lamellar transition-metal oxides and S-based ionic conductors are primarily used as positive electrodes in all-solid-state batteries (ASSBs). However, NMC coatings are necessary to prevent the chemical reactivity of oxygen…
