Low Source/Drain Contact Resistance for AlGaN/GaN HEMTs with High Al Concentration and Si-HP [111] Substrate

Steven Duffy, Brahim Benbakhti, Maghnia Mattalah, Wei Zhang, Meriem Bouchilaoun, Mohammed Boucherta, Karol Kalna, Nour Eddine Bourzgui, Maher, Hassan, Ali Soltani

An optimized fabrication process of ohmic contacts is proposed to reduce the source/drain access resistance (RC) and enhance DC/RF performance of AlGaN/GaN HEMTs with a high Al concentration. We show that source/drain RC can be considerably lowered by (i) optimally etching into the barrier layer…

Acoustic source localization based on the similarity rate between frequency-time images

Karl Hourany, Youssef Zaatar, Farouk Benmeddour, Emmanuel Moulin, Dorothée Debavelaere-Callens, Jamal Assaad

Many studies in different domains have shown the possibility of extracting information from a medium by exploiting the natural acoustic noise present in such medium. Recently, the promising potential of a passive acoustic technique, based on the correlation of the ambient noise for controlling the…

Study of the positioning of wireless sensors for communication at 2.4 GHz inside the train

Ulrich Biaou, Sara Iben Jellal, Michael Bocquet, S. Baranowski, Atika Rivenq, Philippe Mariage

The benefits of wireless sensor networks (WSN) offer many possibilities for the management of energy systems, which are actually based on wired systems. The need of new services on-board the train and of cables lengths reduction promote the use of wireless sensor networks in trains. Then,…

Generation of mW level in the 300-GHz band using resonant-cavity-enhanced unitraveling carrier photodiodes

Philipp Latzel, Fabio Pavanello, Maximilien Billet, Sara Bretin, Alexandre Beck, Mathias Vanwolleghem, Christophe Coinon, Xavier Wallart, Emilien Peytavit, Guillaume Ducournau, Mohammed Zaknoune, Jean-Francois Lampin

We present a resonant-cavity-enhanced broadband unitraveling carrier photodiode optimized for terahertz (THz) generation. It uses a novel semitransparent top-contact utilizing subwavelength apertures for enhanced optical transmission. The contact allows front-side illumination of the photodiode…
