Novel three-dimensional carbon nanotube networks as high performance thermal interface materials

Qinyu Kong, Laurence Bodelot, Bérengère Lebental, Yu Dian Lim, Li Lynn Shiau, Boris Gusarov, Chong Wei Tan, Kun Liang, Congxiang Lu, Chuan Seng Tan, Philippe Coquet, Beng Kang Tay

Vertically aligned carbon nanotube (VACNT) arrays are considered as promising thermal interface materials (TIMs) due to their superior out-of-plane thermal conductivities. However the air gaps between adjacent CNTs within the CNT array hinder the in-plane heat transfer, thus significantly degrading…

Miniaturized Coplanar Waveguide for Nanostructured Magnetostrictive Multilayer Characterization

Abdelhatif El Fellahi, Aurélien Mazzamurro, Jean Claude Gerbedoen, Yannick Dusch, Olivier Bou Matar, Philippe Pernod, Abdelkrim Talbi, Nicolas Tiercelin

A miniaturized coplanar waveguide (CPW) on a Y-cut LiNbO3 substrate operating in Radio Frequency region (RF) is proposed for studying of magnetostrictive multi-layered structure. The structure is composed of a 14 × [TbCo2 (3.7 nm)/FeCo (4 nm)] nanostructured multi-layer. Using microtechnology…

Effect of graphene layer on the localized surface plasmon resonance (LSPR) and the sensitivity in periodic nanostructure

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

We study the interaction of gold nanoparticles with a graphene film. Graphene is used as a spacer, as thin as possible, between the gold nanoparticles and the detection dielectric medium, and one of the advantages of graphene is to protect the structure, which allows to avoid the oxidation of…

Improving performance of OFET by tuning occurrence of charge transport based on pentacene interaction with SAM functionalized contacts

Shuo Li, David Guérin, Kamal Lmimouni

Optimized pentacene thin film transistors have been achieved by two technological self-assembled monolayers (SAM) treatments, with surface modification of 3-octadecyltrichlorosilane (OTS) monolayer on SiO2 dielectric layer and 2,3,4,5,6-pentafluorobenzenethiol (PFBT) monolayer on gold source/drain…
