Scale effects induced by imperfect interfaces in nanomaterials transport properties

Fabio Pavanello, F. Manca, Pier Luca Palla, Evelyne Lampin, Fabrizio Cleri, Stefano Giordano

One of the crucial factors governing the physical properties of nanomaterials is the complex behavior of the interfaces[1]. While at the macroscopic level their specific role is usually neglected, in nanostructured systems the properties of the contact between phases have to be carefully defined....

Distributional upper bound on the interference in spatial wireless multiuser ultrawideband communication systems

Gareth W. Peters, Ido Nevat, Laurent Clavier, François Septier

We develop a novel distributional upper bound on the interference created in an ultra-wideband wireless communication systems under two general assumptions: the first is that there is an unknown number of interferers who are distributed according to a homogeneous Poisson point process randomly in...

From semiconductor nanocrystals to artificial graphene and topological insulator

Efterpi Kalesaki, Christophe Delerue, Cristiane Morais Smith, Wouter Beugeling, Guy Allan, Daniel Vanmaekelbergh

Recent advancements in colloidal chemistry indicate that two-dimensional single-crystalline sheets of semiconductors forming a honeycomb lattice can be synthesized from semiconductor nanocrystals [1]. We perform atomistic tight-binding calculations of the band structure of CdSe sheets with such a...

Theory of self-assembled nanoparticle networks as logic building blocks

Fabrizio Cleri, Sergio Carrillo, Christophe Krzeminski

Recently, self-assembled networks of functionalized nano particles (NPSAN) were proposed as a prototype of innovative devices [1], with switchable NP-NP links. Thanks to the chemical properties of the surface molecules, these would ultimately show memristive behaviour, as building blocks of a...

Focusing capability of a phononic crystal based on a hollow metallic structure

Anne-Christine Hladky, Charles Croënne, Jerome O. Vasseur, Lionel Haumesser, Andrew N. Norris

The dispersion curves of a phononic crystal (PC) based on a hollow metallic structure are presented. They exhibit a negative refraction dispersion branch and perfect refractive index matching with the surrounding water, leading to focusing capability. Numerical and experimental results are reported...

Influence of an interfacial AlxIn1-xSb layer on the strain relaxation and surface morphology of thin GaSb layers epitaxially grown on GaAs(001)

Mathieu Danoy, Pierre-François Angry, Julien Gavrel, Charlène Brillard, L. Desplanque, Y. Wang, P. Ruterana, Xavier Wallart

This work focuses on the strain relaxation and surface morphology of 10 ML thick GaSb layers on GaAs. It is shown that full relaxation is never reached for this thickness. The use of an AlSb interfacial layer only slightly improves strain relaxation but greatly reduces surface roughness. Finally,...
