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…

Tight-binding calculations of the optical properties of HgTe nanocrystals

Guy Allan, Christophe Delerue

We propose a tight-binding model of HgTe which gives an accurate band structure in a wide energy range compared to recent ab initio calculations. The inverted band structure near the Fermi level and its temperature dependence are also very well described. Using this parametrization, we study the…

Development and simulation of a structure based on CuIn1-xGaxSe2 semiconductors alloys for a new generation of photovoltaic cells

Abdelkader Aissat, M. Fathi, Jean-Pierre Vilcot

The aim of our study is the development and simulation of thin films structure based on CuIn1-xGaxSe2 semiconductors alloys to improve the conversion efficiency of solar cells. We studied and simulated the variation effect of the Gallium concentration on some physical and electrical properties (…

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…

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…

Narrow linewidth tunable THz signal radiated by 1.55 µm photomixing

Alain Rolland, Guillaume Ducournau, Goulc'Hen Loas, Alexandre Beck, Fabio Pavanello, Emilien Peytavit, Tahsin Akalin, Mohammed Zaknoune, Jean-Francois Lampin, Marc Brunel, François Bondu, Marc Vallet, Mehdi Alouini

THz has become a wide field of investigation opening new opportunities in a growing number of domains of physics, chemistry, and biology. Among the different techniques existing today to generate THz fields, heterodyning two optical frequencies is a useful approach when tunability is required.…
