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…

Silicon nanotweezers inside liquid for the real time characterization of DNA degradation under radiotherapy treatment

Grégoire Perret, T. Lacornerie, V. Kumemura, N. Lafitte, H. Guillou, L. Jalabert, E. Lartigau, T. Fujii, Fabrizio Cleri, H. Fujita, Dominique Collard

Tumor cell killing by γ-ray beams in radiotherapy is currently based on a rather empirical understanding of the basic mechanisms and effectiveness of DNA damage by radiation. On the other hand, the mechanical behavior of DNA, e.g., sequence-sensitivity, elastic vs. plastic response, is well…

Control of the ionization state of three single donor atoms in silicon

B. Voisin, M. Cobian, X. Jehl, M. Vinet, Yann-Michel Niquet, Christophe Delerue, Silvano de Franceschi, M. Sanquer

By varying the front-gate and the substrate voltages in a short silicon-on-insulator trigate field-effect transistor, we control the ionization state of three arsenic donors. We obtain good quantitative agreement between three-dimensional electrostatic simulations and experiment for the control…

Effects of deposition parameters on the composition of Cu(In,Ga)Se2 thin films deposited by magnetron pulsed DC sputtering

Thomas Aviles, Jean-Pierre Vilcot

Industrial Cu(In,Ga)Se2 (CIGS) thin films formation process generally require two steps : 1) Cu-In-Ga precursors deposition 2) crystallization under selenium atmosphere (H2Se). Unfortunately, hydrogen selenide is very hazardous, being the most toxic selenium compound. Nevertheless, recent works…

A synthesis of theoretical and experimental study on power line communication over an aircraft tree-shaped network

Virginie Degardin, Pierre Laly, M. Lienard, Pierre Degauque

This paper gives an overview of the theoretical and experimental approach which has been carried out in order to study the feasibility of broadband power line communication in aircraft. The network which has been chosen corresponds to part of a cabin lighting system and whose tree shape…
