AlGaN/GaN High Electron Mobility Transistors Grown by MOVPE on 3C-SiC/Si(111) for RF Applications

Marie Lesecq, Eric Frayssinet, Marc Portail, Micka Bah, N. Defrance, Thi Huong Ngo, Mahmoud Abou Daher, Marcin Zielinski, Daniel Alquier, Jean-Claude de Jaeger, Yvon Cordier

In this work, an AlGaN/GaN HEMT structure is grown on a 0.8 μm thick 3C-SiC layer on high resistivity Silicon substrate. The RF propagation losses are investigated and compared with the ones of epi-layers grown directly on Silicon and on 6H-SiC substrates. Short gate length transistors are...

A test methodology to assess the susceptibility of LTE communications in a railway electromagnetic environment

Nathan Chopinet, Virginie Deniau, Eric Pierre Simon, Artur Nogueira de Sao Jose, Jonathan Villain

The LTE communication protocol is more and more employed in the railway domain. Indeed, the LTE throughput enables railway companies to offer Wi-Fi connections to their customers inside the trains. LTE is also used in innovation projects such as remote train control and autonomous trains. However,...

Detection and Classification of Interference affecting LoRaWAN communications in Railway environment

Jonathan Villain, Virginie Deniau, Eric Pierre Simon, Christophe Gransart, Artur Nogueira de São José, Florent Valenti, Norbert Becuwe

The French national railway company (SNCF) is deploying Internet of Things (IoT) technologies using the LoRaWAN communication protocol to centralize and transmit the data measured by the onboard sensors to the railway maintenance centers. They recently developed a communication interface connected...

Deterministic Polarimetric Propagation Analysis in Road Tunnels

Esteban Egea-Lopez, Jose-Maria Molina-Garcia-Pardo, Martine Lienard, Pierre Degauque

The objective of this paper is to study the influence of the direction of polarization at the transmitter site on the characteristics of the propagation channel in a road tunnel, either empty or in presence of vehicles. The transmitting frequency being on the order of 1 GHz, the tunnel behaves as...

Suspended crystalline silicon thermometry devices: towards quantum nanophononics

Jon Canosa, Hafsa Ikzibane, Boris Brisuda, Natalio Mingo, Olivier Bourgeois, Emmanuel Dubois, Jean-François Robillard

This work addresses the current experimental gap in thermal transport regimes and phonon transport at low temperatures and small scales. These conditions cause the wavelength λ and mean free pass Λ of phonons to become equal or greater than the sample’s dimensions, giving rise to several...

Integrated metrology devices dedicated to transient Harman measurement of silicon nano-meshes

Hafsa Ikzibane, Jon Canosa Diaz, Emmanuel Dubois, Jean-François Robillard

In thermoelectricity, silicon nanostructures represent an interesting alternative to conventional thermoelectric materials due to Si abundance, non-toxic nature and its compatibility with CMOS technology. Researchers have investigated methods to enhance the silicon figure of merit zT by increasing...
