Mechanically robust 39 GHz cut-off frequency graphene field effect transistors on flexible substrates

Wei Wei, Emiliano Pallecchi, Samiul Haque, Stefano Borini, Vanessa Avramovic, Alba Centeno, Zurutuza Amaia, Henri Happy

Graphene has been regarded as a promising candidate channel material for flexible devices operating at radio-frequency (RF). In this work we fabricated and fully characterized double bottom-gate graphene field effect transistors on flexible polymer substrates for high frequency applications. We...

Silicon Nanostructures for Photovoltaics

Fabrice Gourbilleau, Ramesh Pratibha Nalini, Julien Cardin, Christian Dufour, Odile Cristini-Robbe, Yannick Lambert, Di Zhou, Tao Xu, Didier Stiévenard

SiOx/SiO2 and SiOx/SiNx multilayers have been grown by reactive magnetron sputtering. Different fabrication parameters have been studied to optimize the density of Si nanoparticles (Si-nps) within the SiOx sublayer. The aim is to favor the optical properties of the film as well as the carrier...

Impact of the bending on the electroluminescence of flexible InGaN/GaN light-emitting diodes

Gema Tabares Jimenez, Sarra Mhedhbi, Marie Lesecq, Benjamin Damilano, Julien Brault, Sebastien Chenot, Abel Ebongue, Philippe Altuntas, N. Defrance, Virginie Hoel, Yvon Cordier

The role that the mother substrate plays to influence the performance of InGaN/GaN-based light-emitting diodes (LEDs) onto the adhesive flexible tapes is addressed in this letter. For this purpose, the electroluminescent (EL) spectra and current density-voltage (J-V) characteristics of flexi-LEDs...

Nonlinear phonon modes in second-order anharmonic coupled monoatomic chains

Bertrand Dubus, N. Swinteck, K. Muralidharan, Jerome O. Vasseur, P. Deymier

We have used multiple-time-scales perturbation theory as well as the numerical methods of molecular dynamics and spectral energy density (SED) to investigate the phonon band structure of a two-chain model with second-order anharmonic interactions. We show that when one chain is linear and the other...

Characterization of the High-Frequency Conducted Electromagnetic Noise Generated by an Arc Tracking Between DC wires

Virginie Degardin, Lamine Kone, Flavien Valensi, Pierre Laly, M. Lienard, Pierre Degauque

In case of a short-circuit between two wires of a dc line, a sustained arc may occur and propagate along the wires through pyrolization of the insulation. This phenomenon, known as arc tracking, is quite critical from a safety point of view since it can cause fire or explosion, depending on its...
