Resolving the Controversial Existence of Silicene and Germanene Nanosheets Grown on Graphite

Wenbing Peng, Tao Xu, Pascale Diener, Louis Biadala, Maxime Berthe, Xiaodong Pi, Yves Borensztein, Alberto Curcella, Romain Bernard, Geoffroy Prévot, B. Grandidier

The highly oriented pyrolytic graphite (HOPG) surface, consisting of a dangling bond-free lattice, is regarded as a potential substrate for van der Waals heteroepitaxy of two-dimensional layered materials. In this work, the growth of silicon and germanium on HOPG is investigated with scanning...

Multimodal imaging technology by integrated scanning electron, force, and microwave microscopy and its application to study microscaled capacitors

Olaf C Haenssler, Sergej Fatikow, Didier Theron

Extracting simultaneously multimodal nanoscale specimen information, by an integrated microscopy technology, is in the focus of this report. The combination of multiple imaging techniques allows for obtaining complementary and often unique datasets of samples under test. An instrumental setup...

Measurement of the thermal conductivity of flexible biosourced polymers using the 3-omega method

Ghizlane Boussatour, Pierre-Yves Cresson, Benoit Genestie, Nicolas Joly, Jean-François Brun, T. Lasri

The thermal conductivity of flexible biosourced polymers was measured by the 3-omega method. Two biopolymers were investigated: the polylactic acid (PLA), a widely used commercial biodegradable one, and the cellulose palmitate (CP), a hydrophobic biosourced material developed in the laboratory,...

Electric field tuning of magnetism in heterostructure of yttrium iron garnet film/lead magnesium niobate-lead zirconate titanate ceramic

Jianyun Lian, Freddy Ponchel, Nicolas Tiercelin, Ying Chen, Denis Remiens, Tuami Lasri, Genshui Wang, Philippe Pernod, Wenbin Zhang, Xianlin Dong

In this paper, the converse magnetoelectric (CME) effect by electric field tuning of magnetization in an original heterostructure composed of a polycrystalline yttrium iron garnet (YIG) film and a lead magnesium niobate-lead zirconate titanate (PMN-PZT) ceramic is presented. The magnetic...

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...

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...

High-resolution THz gain measurements in optically pumped ammonia

Martin Mičica, Sophie Eliet, Mathias Vanwolleghem, Roman Motiyenko, Anastasia Pienkina, Laurent Margulès, Kamil Postava, Jaromír Pištora, Jean-Francois Lampin

This study is aimed at the evaluation of THz gain properties in an optically pumped NH$_3$ gas. NH$_3$ molecules undergo rotational-vibrational excitation by mid-infrared (MIR) optical pumping provided by a MIR quantum cascade laser (QCL) which enables precise tuning to the NH3 infrared transition...

Neuromorphic Time-Dependent Pattern Classification with Organic Electrochemical Transistor Arrays

Sébastien Pecqueur, Maurizio Mastropasq Talamo, David Guérin, Philippe Blanchard, Jean Roncali, Dominique Vuillaume, F. Alibart

Based on bottom‐up assembly of highly variable neural cells units, the nervous system can reach unequalled level of performances with respect to standard materials and devices used in microelectronic. Reproducing these basic concepts in hardware could potentially revolutionize materials and device...
