Generalized interface models for transport phenomena : unusual scale effects in composite nanomaterials

F. Pavanello, F. Manca, Pier Luca Palla, S. Giordano

The effective transport properties of heterogeneous nanoscale materials and structures are affected by several geometrical and physical factors. Among them, the presence of imperfect interfaces plays a central role being often at the origin of the scale effects. To describe real contacts between…

Multifunctional solid/solid phononic crystal

N. Swinteck, Jerome O. Vasseur, Anne-Christine Hladky, Charles Croënne, S. Bringuier, P.A. Deymier

A two-dimensional, solid/solid phononic crystal (PC) comprised a square array of steel cylinders in epoxy is shown to perform a variety of spectral, wave vector, and phase-space functions. Over a range of operating frequencies, the PC’s elastic band structure shows uniquely shaped equifrequency…

Effect of heterostructure design on current-voltage characteristics in AlxGa1-xN/GaN double-barriers resonant tunneling diode

Mohamed Boucherit, Ali Soltani, Michel Rousseau, J.L. Farvacque, Jean-Claude de Jaeger

Ballistic transport in double-barriers resonant tunneling diodes based on GaN is investigated in this work using the non-equilibrium Green's functions formalism. The electron density of states, the electrons concentration, and the current-voltage characteristics are calculated taking into…

Size-dependence of the exciton transitions in colloidal CdTe quantum dots

Esther Groeneveld, Christophe Delerue, Guy Allan, Yann-Michel Niquet, Celso de Mello Donega

In this paper, we present a detailed investigation of the size dependence of the optical transitions of colloidal CdTe QDs ranging in diameter from 2.9 to 14.8 nm. The energy integrated absorption cross section per CdTe unit is investigated in detail for the lowest two exciton transitions (1S3/2(h…

Nanometer-scale, quantitative composition mappings of InGaN layers from a combination of scanning transmission electron microscopy and energy dispersive x-ray spectroscopy

K. Pantzas, G. Patriarche, David Troadec, S. Gautier, T. Moudakir, S. Suresh, L. Largeau, O. Mauguin, P. L. Voss, A. Ougazzaden

Using elastic scattering theory we show that a small set of energy dispersive x-ray spectroscopy (EDX) measurements is sufficient to experimentally evaluate the scattering function of electrons in high-angle annular dark field scanning transmission microscopy (HAADF-STEM). We then demonstrate how…

Hertz-Mindlin problem for arbitrary oblique 2D loading : general solution by memory diagrams

Vladislav Aleshin, Koen van den Abeele

In this paper we present a new general solution to the fundamental problem of frictional contact of two elastic spheres, also known as the Hertz–Mindlin (HM) problem. The description of spheres in contact is a central topic in contact mechanics. It became a foundation of many applications, such as…
