Terahertz time-domain spectroscopy of absorbing materials and of metamaterials

Jean-Louis Coutaz, M. Bernier, Frédéric Garet, S. Joly, Y. Miyake, H. Minamide, Eric Lheurette, Didier Lippens

This paper gives a review of recent works we performed in view of characterizing natural materials and metamaterials by terahertz time-domain spectroscopy. We address materials that exhibit a low transmittance in given narrow spectral bands or over the whole experimental spectral window. We give...

Step-conformal deposition of TiO2 and MnO2 electrodes on advanced silicon microstructures for 3D Li-ion microbatteries and micro-supercapacitors

Étienne Eustache, Camille Douard, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Thierry Brousse, Christophe Lethien

To get autonomous smart microsystem, a miniaturized power source should be integrated. As the device is surface limited, the energy and power performances of commercially available planar microbatteries and micro-supercapacitors are not sufficient to reach this goal. To improve their performances...

On the effect of δ-doping in self-switching diodes

Andreas Westlund, Ignacio Iñiguez-De-La-Torre, Per-Åke Nilsson, Tomas González, Javier Mateos, Paul Sangaré, Guillaume Ducournau, Christophe Gaquière, L. Desplanque, Xavier Wallart, Jan Grahn

Lowering the carrier concentration is presented as a way to considerably improve the performance of self-switching diode (SSD) detectors. A physics-based theoretical model was used to derive an expression for the responsivity of SSDs as a function of carrier concentration, mobility, and design...

Dirac cones, topological edge states, and nontrivial flat bands in two-dimensional semiconductors with a honeycomb nanogeometry

Efterpi Kalesaki, Christophe Delerue, Cristiane Morais Smith, Wouter Beugeling, Guy Allan, Daniel Vanmaekelbergh

We study theoretically two-dimensional single-crystalline sheets of semiconductors that form a honeycomb lattice with a period below 10 nm. These systems could combine the usual semiconductor properties with Dirac bands. Using atomistic tight-binding calculations, we show that both the atomic...

Modeling and simulation of AlxGayIn1-x-yAs/InP quaternary structure for photovoltaic

Abdelkader Aissat, M. El Bey, Rachid Bestam, Jean-Pierre Vilcot

In this work, we have studied solar cells based on AlGaInAs/InP quaternary structure to describe the behavior of electronics components. To this end, we have developed a simulation program to study the gallium Ga and aluminum Al concentrations effect on respectively the lattice mismatch, the band...

Guided wave in multilayered piezoelectric-piezomagnetic bars with rectangular cross-sections

J.G. Yu, Jean-Etienne Lefebvre, C. Zhang

For the purpose of design and optimization of multilayered piezoelectric-piezomagnetic material (PPC) transducers, wave propagation in these structures has received much attention in past ten years. But the research objects of previous works are only for semi-infinite structures and one-dimensional...
