Synthesis and electrical conductivity of multilayer silicene

Patrick Vogt, Pierre Capiod, Maxime Berthe, Andrea Resta, Paola de Padova, Thomas Brühne, Guy Le Lay, B. Grandidier

The epitaxial growth and the electrical resistance of multilayer silicene on the Ag(111) surface has been investigated. We show that the atomic structure of the first silicene layer differs from the next layers and that the adsorption of Si induces the formation of extended silicene terraces…

Ferroelectric thin films working at microwave frequency for reconfigurable devices on silicon substrate: performances comparison between BST, PST

Freddy Ponchel, Denis Remiens, Areski Ghalem, Tuami Lasri

The dielectric microwave performance of BST and PST films is studied via tunability. The films are deposited onto silicon wafer with high resistivity using radio frequency magnetron sputtering with an in situ process for BST films and ex situ for PST films. In order to improve the crystalline…

High performance TiN gate contact on AlGaN/GaN transistor using a mechanically strain induced P-doping

Ali Soltani, Michel Rousseau, Jean-Claude Gerbedoen, Maghnia Mattalah, P.L. Bonanno, A. Telia, Nour Eddine Bourzgui, Gilles Patriarche, A. Ougazzaden, A. Ben Moussa

High performance titanium nitride sub-100 nm rectifying contact, deposited by sputtering on AlGaN/GaN high electron mobility transistors, shows a reverse leakage current as low as 38 pA/mm at VGS = -40 V and a Schottky barrier height of 0.95 eV. Based on structural characterization and 3D…

Optomechanic interaction in a corrugated phoxonic nanobeam cavity

Mourad Oudich, Said El-Jallal, Yan Pennec, Bahram Djafari-Rouhani, Jordi Gomis-Bresco, Daniel Navarro-Urrios, Clivia M. Sotomayor Torres, Alejandro Martínez, Abdelkader Makhoute

The interaction between phonons and photons is investigated theoretically in a phoxonic cavity inside a corrugated nanobeam waveguide presenting band gaps for both electromagnetic and elastic waves. The structure is made by drilling periodic holes on a silicon nanobeam with lateral periodic stubs…

Transport properties of CdSe nanocrystal superlattice

Pierre Capiod, Maxime Berthe, B. Grandidier, Wiel Evers, Daniel Vanmaekelbergh

Two-dimensional materials exhibit exotic electronic properties and high specific surface areas that make them unique to investigate novel physical phenomena. In addition, their two-dimensional geometry is directly compatible with established design and processing approaches from the semiconductor…

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…
