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 (…

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…

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…

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…

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…

Structure and electrical properties in the K1/2Bi1/2TiO3-K1/2Bi1/2ZrO3 solid solution (KBT-KBZ)

M. Bengagi, François Morini, M. El Maaoui, Pascal Marchet

The present work is devoted to the study of the Zr 4þ /Ti 4 substitution in the K1/2Bi1/2Ti(1-x)ZrxO3 solid solution (x ¼ 0.0 to x ¼ 1.0), based upon the K1/2Bi1/2TiO3 (KBT) ferroelectric compound. The tetragonal distortion of KBT is suppressed by this substitution and leads to the cubic compound…
