0.53 mΩ.cm 2 /592 V High Breakdown Voltage GaN-on-Sapphire Schottky Diodes Without Edge Termination

Hugo Bouillaud, Beatriz Orfao, Etienne Okada, Yannick Roelens, Malek Zegaoui, Mohammed Zaknoune

In this letter, we report high-performance Pt/GaN quasi-vertical Schottky barrier diodes on sapphire substrate. With a 5 μm drift layer and a highly controlled fabrication process, the devices demonstrate an extremely low on-resistance of 0.53 mΩ.cm² while exhibiting a high breakdown voltage of 592…

Ultralow‐Dispersion Silicon THz Photonic Crystal Interconnects for Multichannel Datalinks

Nikhil Navaratna, Thomas Caiwei Tan, Pascal Szriftgiser, Guillaume Ducournau, Ranjan Singh

All-Silicon (Si) Terahertz (THz) interconnects are a key platform for next-generation on-chip communication, leveraging broadband photonics to connect reconfigurable electronics. Yet their potential remains largely unrealized, due to low reported data rates and a lack of systematic insight into the…

Far-Field Terahertz Spectroscopy of a Subwavelength Single Planar Meta-Atom

Surya Revanth Ayyagari, Simonas Indrišiūnas, Guillaume Ducournau, Vytautas Janonis, Irmantas Kašalynas

Accurate measurements of light-matter interactions at subwavelength scales are critical for advancing nanophotonic and quantum optical technologies. In this paper, we present the far-field terahertz (THz) spectroscopy of a single planar meta-atom of subwavelength dimensions embedded within a square…

Real-Time Evolution of the Mechanical Properties of Flax Stems During Post-Harvest Dew Retting: Towards Objective Retting Assessment

Ali Reda, Lionel Buchaillot, Steve Arscott

Post-harvest field dew retting is a critical stage in flax fibre production because it facilitates the separation of fibre bundles from the surrounding stem tissues. In current agricultural practice, the optimum retting stop-point is still assessed largely using empirical criteria, motivating the…

Steerable Thin-Film Electrode Array for Cochlear Implantation: Design and Development for Future Atraumatic Insertion

Ahmad Itawi, Bacem Zribi, Prabhakar Sidambaram, Thanh Hang Tran, Guillaume Tourrel, Renato Torres, Sofiane Ghenna, Sébastien Grondel, Yann Nguyen, Cedric Plesse, Eric Cattan

During cochlear implant surgery, standard electrode arrays are inserted into the scala tympani to stimulate the spiral ganglion cells and rehabilitate hearing in deaf patients. However, conventional electrode arrays' stiffness and passive nature lead to potential trauma or incomplete insertion…

Plant- and Microalgae-Based Biotechnological Strategies for Affordable and Non-Invasive Delivery of Antidiabetic Peptides

Thibault Boscart, Alexandre Barras, Valérie Plaisance, Valérie Pawlowski, Emerson Giovanelli, Muriel Bardor, Christophe D’hulst, Amar Abderrahmani

The prevalence of diabetes and its worldwide co-morbidities is escalating. Therefore, the number of users of therapeutic peptides including insulin analogs and glucagon-like peptide 1 receptor agonists (GLP-1RAs), will unavoidably increase in the coming years. However, access to these two…
