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…

Inkjet-Printing with Micrometer Resolution on Paper for Flexible RF Applications

Fawzi Bouakkaz, Riccardo Sargeni, Sylvie Lepilliet, Simon Skrzypczak, Emiliano Pallecchi, Gianluca Fiori, Henri Happy

Geometry is a critical factor in radio frequency design that directly affects the performance and efficiency of RF components and systems. The characteristic impedance and the propagation constant of transmission lines are affected by the conductor width, spacing, and the dielectric properties. In…

Low-loss, 1-m long length, silica based hollow-core THz waveguide operating at 1 THz

Georges Humbert, Jean-Louis Auguste, Guillaume Ducournau, Jean-Francois Lampin

A hollow-core THz waveguide composed of silica capillaries is proposed for low-loss THz wave propagation. Silica, despite its large absorption coefficient at THz frequencies, offers numerous fabrication advantages for developing THz waveguides. A numerical study on the anti-resonant guiding…
