Towards highly efficient high power X‐band AlN/GaN MIS HEMTs operating above 50V

Kathia Harrouche, Sri Saran Vankatachalam, François Grandpierron, Etienne Okada, F Medjdoub

We report on AlN/GaN MISHEMT technology on SiC substrate for X-band applications. Transistors with 100 nm gate lengths deliver a high off-state breakdown voltage above 180V and 110 V in semi-on state. RF small signal measurements up to a drain bias (VDS) as high as 70V for two different gate…

Band structure tuning at (La,Sr)MnO3 / (Ba,Sr)TiO3 interface

Jérôme Wolfman, Antoine Ruyter, B. Negulescu, Pascal Andreazza, Xavier Wallart, Sylvie Schamm-Chardon, Robin Cours, Teresa Hungria, Cecile Autret

Band structure engineering in silicon-based heterostructures dedicated to microelectronic and energy harvesting applications has been common material scientist playground for decades. Careful design of the energy level variation at hetero-interfaces is used e.g. to collect electron while preventing…

100 Gbit/s THz Data Transmission and Beyond using Multicore Fiber Combined with UTC Photodiode Array

Alfred Bewindin Sawadogo, Aritrio Bandyopadhyay, Malek Zegaoui, Mohammed Zaknoune, P. Szriftgiser, Karen Baudelle, Monika Bouet, Géraud Bouwmans, Davy Gaillot, Esben Ravn Andresen, Guillaume Ducournau, Laurent Bigot

Photonics-driven transmitters are leading the race towards high data-rates at THz frequencies. Here, spatial-multiplexing based on multicore fiber and photodiodes array is considered to alleviate the limited output power. Sub-systems have been developed and validated.

Pairing cells of different sizes in a microfluidic device for immunological synapse monitoring

Faruk Azam Shaik, Clara Lewuillon, Aurélie Guillemette, Bahram Ahmadian, Carine Brinster, Bruno Quesnel, Dominique Collard, Yasmine Touil, Loïc Lemonnier, Mehmet Tarhan

Analyzing cell–cell interaction is essential to investigate how immune cells function. Elegant designs have been demonstrated to study lymphocytes and their interaction partners. However, these devices have been targeting cells of similar dimensions. T lymphocytes are smaller, more deformable, and…

Precoded Large Scale Multi‐User‐MIMO System Using Likelihood Ascent Search for Signal Detection

Kalapraveen Bagadi, Chinthaginjala V. Ravikumar, Mohammad Alibakhshikenari, Nagaraj Challa, A. Rajesh, Sonia Aïssa, Iyad Dayoub, Francisco Falcone, Ernesto Limiti

Multiple antennas at each User Equipment (UE) and/or thousands of antennas at the Base Station comprise the extremely spectrum efficient large scale Multi-User Multiple Input Multiple Output (MU-MIMO) system (BS). Due to space constraints, the closely spaced numerous antennas at each UE may cause…
