20 Gbit/s 306 GHz link enabled by Yagi-Uda antenna

Guillaume Ducournau, Fabio Pavanello, Aritrio Bandyopadhyay, Cybelle Belem-Gonçalves, Frédéric Gianesello, Cyril Luxey, Emilien Peytavit, Jean-Francois Lampin, Malek Zegaoui, Mohammed Zaknoune

We report on the use of a Yagi-Uda antenna on polymer substrate used in a 306 GHz-20 Gbit/s real-time data link for indoor applications. The Yagi-Uda antenna is described and the validation of the THz link is obtained in amplitude modulation mode and using QAM-16 signals (32 Gbit/s).

Nanoprobe study of the electric field driven insulator-to-metal transition in GaMo4S8

H. Koussir, Isabelle Lefebvre, Maxime Berthe, B. Grandidier, Pascale Diener, J. Tranchant, Benoit Corraze, Etienne Janod, Laurent Cario

The resistive switching observed under electric pulses in Mott materials has a high potential for micro and nanoelectronics. Here we report on the study of the resistive switching observed at the surface of single crystals of the canonical Mott semiconductor GaMo4S8. The study is made using a…

Preanalytical issues and cycle threshold values in SARS-CoV-2 real-time RT-PCR testing: should test results include these?

Ilka Engelmann, Enagnon Kazali Alidjinou, Judith Ogiez, Quentin Pagneux, Sana Miloudi, Ilyes Benhalima, Mahdi Ouafi, Famara Sané, Didier Hober, Alain Roussel, Christian Cambillau, David Devos, Rabah Boukherroub, Sabine Szunerits

Since the emergence of SARS-CoV-2 pandemic, clinical laboratories worldwide are overwhelmed with SARS-CoV-2 testing using the current gold standard: real-time reverse-transcription polymerase chain reaction (RT-PCR) assays. The large numbers of suspected cases led to shortages in numerous reagents…

H-Band Substrate-Integrated Discrete-Lens Antenna for High Data Rate Communication Systems

Kossaila Medrar, Loïc Marnat, Laurent Dussopt, Cybelle Belem-Gonçalves, Guillaume Ducournau, Cyril Luxey, Frédéric Gianesello

A substrate-integrated discrete-lens antenna manufactured in standard printed-circuit-board (PCB) technology is demonstrated in H-band (225-325 GHz). The arrays composed of phase-shifting unit cells and a waveguide-fed planar focal source are designed on a single PCB stack with five metal layers…

Piezoresistance in defect-engineered silicon

Heng Li, Abel Thayil, Chris Lew, Marcel Filoche, Brett Johnson, Jeff Mccallum, S. Arscott, Alistair C. H. Rowe

The steady-state, space-charge-limited piezoresistance (PZR) of defect-engineered, silicon-on-insulator device layers containing silicon divacancy defects changes sign as a function of applied bias. Above a punch-through voltage (Vt) corresponding to the onset of a space-charge-limited hole current…
