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…

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…

Indoor radio channel characterization at 60 GHz

Maríateresa Martínez Inglés, Juan Pascual García, José Víctor Rodríguez, José María Molina García-Pardo, Leandro Juan Llácer, Davy Gaillot, M. Lienard, Pierre Degauque

This TD presents a set of 10x10 MIMO measurements at 60GHz in an indoor environment. A theoretical and experimental analysis has been done by means of a 3D ray tracing tool and the high resolution parameter estimator RiMAX. Results show the complexity of modeling the radio channel at the mmW…

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…

Investigation of optical and chemical bond properties of hydrogenated amorphous silicon nitride for optoelectronics applications

Etienne Herth, H Desré, Emmanuelle Algré, Christiane I. Legrand, Tuami Lasri

The aim of this work is to determine optimal deposition parameters of silicon nitride for optical applications. The authors present the investigation of hydrogenated amorphous silicon nitride SiNx:H deposited by the low temperature PECVD method in high frequency reactors. The study of hydrogen…
