Magnetic-Phase Dependence of the Spin Carrier Mean Free Path in Graphene Nanoribbons

Jing Li, Yann-Michel Niquet, Christophe Delerue

We show theoretically that the intrinsic (phonon-limited) carrier mobility in graphene nanoribbons is considerably influenced by the presence of spin-polarized edge states. When the coupling between opposite edges switches from antiferromagnetic to ferromagnetic with increasing carrier density, the…

METASTABILITY OF FINITE STATE MARKOV CHAINS: A RECURSIVE PROCEDURE TO IDENTIFY SLOW VARIABLES FOR MODEL REDUCTION

Claudio Landim, T. Xu

Consider a sequence (η N (t) : t ≥ 0) of continuous-time, irreducible Markov chains evolving on a fixed finite set E. Denote by R N (η, ξ) the jump rates of the Markov chain η N t , and assume that for any pair of bonds (η, ξ),

DS-UWB and TH-UWB Energy Consumption Comparison

Adil Elabboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

The energy consumption of the wireless communication systems is starting to be unaffordable. One way to improve the power consumption is the optimization of the communication techniques used by the communication networks and devices. In order to develop an energy efficient UWB multi-user…

AlN/IDT/AlN/Sapphire SAW Heterostructure for High-Temperature Applications

Ouarda Legrani, Thierry Aubert, Omar Elmazria, Ausrine Bartasyte, Pascal Nicolay, Abdelkrim Talbi, Pascal Boulet, Jaafar Ghanbaja, Denis Mangin

Recent studies have evidenced that Pt/AlN/Sapphire SAW devices are promising for high-temperature high-frequency applications. However, they cannot be used above 700°C in air atmosphere as the Pt interdigital transducers (IDTs) agglomerate and the AlN layer oxidizes in such conditions. In this…

Inverse saffman-taylor experiments with particles lead to capillarity driven fingering instabilities

Ilyesse Bihi, Michael Baudoin, Jason E. Butler, Christine Faille, Farzam Zoueshtiagh

Using air to displace a viscous fluid contained in a Hele-Shaw cell can create a fingering pattern at the interface between the fluids if the capillary number exceeds a critical value. This Saffman-Taylor instability is revisited for the inverse case of a viscous fluid displacing air when partially…

Investigation of the Effect of Plasma Polymerized Siloxane Coating for Enzyme Immobilization and Microfluidic Device Conception

Kalim Belhacene, Adil Elagli, Céline Vivien, A. Treizebre, Pascal Dhulster, Philippe Supiot, Renato Froidevaux

This paper describes the impact of a physical immobilization methodology, using plasma polymerized 1,1,3,3, tetramethyldisiloxane, on the catalytic performance of β-galactosidase from Aspergillus oryzae in a microfluidic device. The β-galactosidase was immobilized by a polymer coating grown by…
