Perspective: organic electronic materials and devices for neuromorphic engineering

Sébastien Pecqueur, Dominique Vuillaume, F. Alibart

Neuromorphic computing and engineering has been the focus of intense research efforts that have been intensified recently by the mutation of Information and Communication Technologies (ICT). In fact, new computing solutions and new hardware platforms are expected to emerge to answer to the new…

Strain-Reduction Induced Rise in Channel Temperature at Ohmic Contacts of GaN HEMTs

Steven Duffy, Brahim Benbakhti, Karol Kalna, Mohammed Boucherta, Wei Zhang, Nour Eddine Bourzgui, Ali Soltani

ABSTRACT Operating temperature distributions in AlGaN/GaN gateless and gated devices are characterized and analyzed using the InfraScope temperature mapping system. For the first time, a substantial rise of channel temperature at the inner ends of ohmic contacts has been observed. Synchrotron…

Gallium nitride MEMS resonators: how residual stress impacts design and performances

Christophe Morelle, Didier Theron, Joff Derluyn, Stefan Degroote, Marianne Germain, Victor Zhang, Lionel Buchaillot, Bertrand Grimbert, Pascal Tilmant, Francois Vaurette, Isabelle Roch-Jeune, Virginie Brandli, Vanessa Avramovic, Etienne Okada, Marc Faucher

Starting from Gallium Nitride epitaxially grown on silicon, pre-stressed micro-resonators with integrated piezoelectric transducers have been designed, fabricated, and characterized. In clamped-clamped beams, it is well known that tensile stress can be used to increase the resonant frequency. Here…

A dual-bandwearable exposure meter for personal RF exposure assessment in indoor environments: on-body calibration in a reverberation chamber

Reza Aminzadeh, Arno Thielens, Davy Gaillot, M. Lienard, Sam Agneessens, Patrick van Torre, Matthias van den Bossche, Hendrik Rogier, Martin Roosli, Luc Martens, Wout Joseph

For the first time, a dual band wearable personal distributed exposure meter (DPDE) is designed. The DPDE is calibrated on-body in a reverberation chamber. The meter consists of four nodes including textile antennas operating at 2443 MHz (WiFi 2 GHz) and 2595 MHz (LTE 2600 MHz). The location of the…

Ultra-low loss ridge waveguides on lithium niobate via argon ion milling and gas clustered ion beam smoothening

Shawn Yohanes Siew, Eric Jun Hao Cheung, Haidong Liang, Andrew Bettiol, Noriaki Toyoda, Bandar Alshehri, El Hadj Dogheche, Aaron J. Danner

Lithium niobate's use in integrated optics is somewhat hampered by the lack of a capability to create low loss waveguides with strong lateral index confinement. Thin film single crystal lithium niobate is a promising platform for future applications in integrated optics due to the availability…

Cyber Security of the Railway wireless system: detection, decision and Human-in-the-Loop

Christophe Gransart, Virginie Deniau, Eric Pierre Simon, Anthony Fleury, Stéphane Lecoeuche, Emilie Masson, Patrick Millot

The networks used in the Railway domain are usually heterogeneous, not enough protected and not fitted to the usual Cyber Security requirements in terms of sustainability, protection and attack detection. Furthermore, the quick evolution of the telecommunication means, the threats and the…

Acoustic analogue of electromagnetically induced transparency and Autler-Townes splitting in pillared metasurfaces

Yabin Jin, Yan Pennec, Bahram Djafari-Rouhani

Electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) originating from multilevel atomic systems have similar transparency windows in transmission spectra which causes confusion when discriminating between them, despite the difference in their physical mechanisms. Indeed…

Unambiguous real-time terahertz frequency metrology using dual 10 GHz femtosecond frequency combs

Oliver Kliebisch, Dirk Heinecke, S Barbieri, Giorgio Santarelli, Hua Li, Carlo Sirtori, Thomas Dekorsy

Terahertz frequency metrology by radio frequency downconversion using femtosecond optical sampling relies on the harmonic factor retrieval between the terahertz frequency and the optical sampling rate. At typical femtosecond laser repetition rates, this imposes an ambiguity for frequency metrology…

Dynamics of the stress-mediated magnetoelectric memory cell N×(TbCo2/FeCo)/PMN-PT

Vladimir Preobrazhensky, Alexey Klimov, Nicolas Tiercelin, Yannick Dusch, Stefano Giordano, Anton Churbanov, Theo Mathurin, Philippe Pernod, Alexander Sigov

Stress-mediated magnetoelectric heterostructures represent a very promising approach for the realization of ultra-low energy Random Access Memories. The magnetoelectric writing of information has been extensively studied in the past, but it was demonstrated only recently that the magnetoelectric…
