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…

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…

Train accurate localization using ultra wide band radio and time reversal

Bouna Fall, Fouzia Elbahhar, Marc Heddebaut, Atika Rivenq

In guided transport, the precise localization of trains is vital for nominal operation of the transport system. In a propagation environment such as a railway line, an effective localization sensor is complex to design since it must operate in the presence of many fixed and mobile obstacles…

Mesure de la permittivité complexe du polydimethylsiloxane (PDMS) jusqu'à 220 GHz pour la mise en oeuvre d'une électronique souple

Pierre-Yves Cresson, Yovan Orlic, Jean-François Legier, Erick Paleczny, Luc Dubois, Philippe Coquet, Nicolas Tiercelin, Sami Hage-Ali, Philippe Pernod, Vladimir Preobrazhensky, Tuami Lasri

Des lignes coplanaires sont réalisées sur un film souple de Polydimethylsiloxane (PDMS) de 182 μm d'épaisseur. Après avoir mesuré les paramètres [S] de ces lignes, des algorithmes ajustent la permittivité complexe du matériau pour que les valeurs des constantes de propagation extraites des…

200 GHz coherent wireless link using photonics-based emission

Guillaume Ducournau, Y. Yoshimizu, S. Hisatake, F. Pavanello, Emilien Peytavit, Mohammed Zaknoune, T. Nagatsuma, Jean-Francois Lampin

We investigated a coherent THz link at 200 GHz, with variable data rate up to 11 Gbit/s, featuring the combination of a quasi-optic UTC-PD emitter and a high sensitivity electronic receiver. This coherent link relies on an optical frequency comb generator at emission to produce an optical beat note…

Improved efficiency by the effect of strain on the structure of a solar cell based on GaInP/GaAs

Abdelkader Aissat, Rachid Bestam, Jean-Pierre Vilcot

This work is aimed at the study of GaInP-based photovoltaic cell. The effects of In content, lattice parameter mismatch and thickness of the SiO2 insulating layer on the characteristics and efficiency of the GaInP structure were investigated. We noticed that for higher In concentrations, the band…
