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…

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…
