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…

THz power divider circuits on planar Goubau lines (PGLs)

A. Treizebre, Simon Laurette, Yansheng Xu, Renato G. Bosisio, Bertrand Bocquet

Terahertz spectroscopy is a new tool for real time biological analysis. Unfortunately, investigations on aqueous solutions remain difficult and need to work on nanovolumes. Integrated Terahertz instrumentation remains a challenge. We demonstrate that Planar Goubau Line (PGL) technology could bring…

Corrugated Goubau lines to slow down and confine THz waves

Simon Laurette, A. Treizebre, Bertrand Bocquet

Corrugations on planar Goubau lines are presented in order to slow down and focus electromagnetic waves. A propagation effective index shift is observed between corrugated and non-corrugated planar Goubau lines. Influence of the corrugation geometrical parameters is studied. Two original methods…

Low cost 60 GHz new thin pyralux membrane antennas FED by substrate integrated waveguide

Tristan Sarrazin, Hamsakutty Vettikalladi, Olivier Lafond, Mohamed Himdi, Nathalie Rolland

A low cost technology based on FR4 and thin flexible Pyralux substrate to develop membrane antennas/array with high efficiency and wide bandwidth for high speed V-band communication systems is proposed in this paper. A new low cost thin Pyralux substrate with a thickness of 75 μm, relative…
