Purification for Carbon Nanotubes Synthesized by Flame Fragments Deposition via Hydrogen Peroxide and Acetone

Asmaa Hammadi, Ahmed Jasim, Firas Abdulrazzak, Abdulkareem Al-Sammarraie, Yacine Cherifi, Rabah Boukherroub, Falah Hussein

Carbon nanotubes (CNTs) are synthesized by the flame fragment deposition (FFD) technique using Iraqi liquefied petroleum gas (LPG) as a source of carbon in a hand-made reactor at a low temperature (160 °C) without using a catalyst. Purification of the multi-walled carbon nanotubes (MWCNTs) is…

Power-efficient reliable register file for aggressive-environment applications

Ihsen Alouani, Hamzeh Ahangari, Özcan Özturk, Smail Niar

In a context of increasing demands for on-board data processing, insuring reliability under reduced power budget is a serious design challenge for embedded system manufacturers. Particularly, embedded processors in aggressive environments need to be designed with error hardening as a primary goal,…

Development of High Frequency Interdigital Transducers for NDT of Thin Films

Tahar Kadi, Marc Duquennoy, Mohammadi Ouaftouh, Nikolay Smagin, Frédéric Jenot

Various engineering systems components suffer destructive effects on their surfaces, like wear, fatigue, or corrosion during their operation. Protecting the surface by hardening treatments or applying coatings is a widespread way to extend their life and improve the product quality. Important…

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…

Caractérisation et modélisation de composants terahertz, Charactersation and modeling of terahertz devices

Kévin Froberger

Le domaine térahertz est un domaine de fréquences de plus en plus étudié à cause des propriétés particulières de ce rayonnement. La faible énergie des photons permet notamment de faire de l’imagerie médicale, du contrôle non destructif dans l’industrie ou encore d’étudier les astres qui nous…, The terahertz domain is a frequency range, which interest keeps growing because of its properties. Because of the low energy of the photons, it becomes possible to use it for medical imaging, non destructive testing in the industry or even learn about the celestial objects around us. Its high…
