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…

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…

High Breakdown Voltage GaN Schottky Diodes for THz Frequency Multipliers

G. Di Gioia, E. Frayssinet, M. Samnouni, V. Chinni, P. Mondal, J. Treuttel, X. Wallart, M. Zegaoui, Guillaume Ducournau, Yannick Roelens, Yvon Cordier, Mohamed Zaknoune

Quasi-vertical gallium nitride (GaN) Schottky diodes on silicon carbide (SiC) substrates were fabricated for frequency multiplier applications. The epitaxial structure employed had an n− layer of 590 nm with doping 6.6 × 1016 cm−3, while the n+ layer was 950 nm thick, with doping 2 × 1019 cm−3.…

Sub‐Micron thick Step‐Graded AlGaN Buffer on Silicon with a High Buffer Breakdown Field

Elodie Carneiro, Stéphanie Rennesson, Sebastian Tamariz, Kathia Harrouche, Fabrice Semond, Farid Medjdoub

We report on a sub-micron thick AlGaN/GaN high electron mobility transistor (HEMT) epilayers grown on silicon substrate with a state-of-the art vertical buffer breakdown field as high as 6 MV/cm enabling a high transistor breakdown voltage of 250 V for short gate to drain distances despite such a…

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…
