A terahertz wireless communication link using a superheterodyne approach

Iulia Dan, Guillaume Ducournau, Shintaro Hisatake, Pascal Szriftgiser, Ralf-Peter Braun, Ingmar Kallfass

This article presents a wireless communication point-to-point link operated in the low terahertz (THz) range, at a center frequency of 300 GHz. The link is composed of all-electronic components based on monolithic millimeter wave integrated circuits fabricated in an InGaAs metamorphic high electron…

Numerical analysis of a tubular phononic crystal sensor

A. Gueddida, Yan Pennec, S. Hemon, F. Lucklum, M. Vellekoop, N. Mukhin, R. Lucklum, B. Bonello, Bahram Djafari-Rouhani

We present a theoretical investigation of the dispersion and transmission properties of a tubular phononic crystal for sensing application. We show the existence of modes confined in a cavity with displacement field spreading over both the solid and fluid parts. Therefore, the frequency of the…

Aerodynamic wall pressure measurement using a high temperature gradient Pirani micro-sensor

Cécile Ghouila-Houri, Munique Kazar Mendes, Thomas Arnoult, Romain Viard, Quentin Gallas, Eric Garnier, Alain Merlen, Abdelkrim Talbi, Philippe Pernod

This paper presents and discusses the first demonstration of aerodynamic wall pressure measurement using a thermal Pirani effect based micro-sensor. The thermal micro-sensor is designed as a suspended micro-hot-wire separated from the substrate by a nanoscale gap, and mechanically supported by…

Negatively Charged Excitons in CdSe Nanoplatelets

Elena V Shornikova, Dmitri R Yakovlev, Louis Biadala, Scott A Crooker, Vasilii V Belykh, Mikhail V Kochiev, Alexis Kuntzmann, Michel Nasilowski, Benoit Dubertret, Manfred Bayer

Energy Trion Exciton The low-temperature emission spectrum of CdSe colloidal nanoplatelets (NPLs) consists of two narrow lines. The high-energy line stems from the recombination of neutral excitons. The origin of the low-energy line is currently debated. We experimentally study the spectral shift,…

Velocity saturation effect on low frequency noise in short channel single layer graphene field effect transistors (FETs)

Nikolaos Mavredakis, Wei Wei, Emiliano Pallecchi, Dominique Vignaud, Henri Happy, Ramon Garcia Cortadella, Andrea Bonaccini Calia, Jose Garrido, David Jiménez

Graphene devices for analog and radio frequency (RF) applications are prone to low frequency noise (LFN) due to its up conversion to undesired phase noise at higher frequencies. Such applications demand the use of short channel graphene transistors (GFETs) that operate at high electric fields in…
