Experimental evidence of zero-angle refraction and acoustic wave-phase control in a two-dimensional solid/solid phononic crystal

Jerome O. Vasseur, B. Morvan, A. Tinel, N. Swinteck, Anne-Christine Hladky, P.A. Deymier

The square symmetry of the equifrequency contour of longitudinal waves in a solid/solid two-dimensional phononic crystal (PC) is shown through numerical calculations and experiments to lead to peculiar propagation phenomena. A slab of steel/epoxy PC immersed in water refracts incident longitudinal…

A study on millimetre-wave tunable bandpass filter based on polymer cap deflection

S. Seok, J.G. Kim, N. Rolland, P.A. Rolland

This paper presents a new tuning mechanism for millimetre-wave BPF based on deflection of the BCB membrane of BCB packaging cap. A 3-pole parallel-coupled microstrip filter operating at 60 GHz is first implemented on 30 µm-thick BCB polymer substrate and then BCB-capped through our new anti-…

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…

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…

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…
