Synthesis and electrical characterisations of a low work function cesium oxide coating for high efficiency thermionic energy converter

François Morini, J.F. Robillard, Stéphane Monfray, I.D. Baikie, Thomas Skotnicki, Emmanuel Dubois

One main challenge associated with solid-state thermoelectric materials is to combine electron-crystal electrical conductivity and phonon-glass thermal properties that are difficult to conciliate. A markedly different principle of thermoelectric conversion is based on the micro-thermionic generator...

Dispersion properties and low infrared optical losses in epitaxial AlN on sapphire substrate in the visible and infrared range

Ali Soltani, Arnaud Stolz, Joël Charrier, Maghnia Mattalah, Jean-Claude Gerbedoen, Hassan Ali Barkad, Vincent Mortet, Michel Rousseau, Nour Eddine Bourzgui, Ali Benmoussa, Jean-Claude de Jaeger

Optical waveguiding properties of a thick wurtzite aluminum nitride highly [002]-textured hetero-epitaxial film on (001) basal plane of sapphire substrate are studied. The physical properties of the film are determined by X-ray diffraction, atomic force microscopy, microRaman, and photocurrent...

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...

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...

Preparation and study of 2-D semiconductors with Dirac type bands due to the honeycomb nanogeometry

Efterpi Kalesaki, Mark Pieter Boneschanscher, Jaco J. Geuchies, Christophe Delerue, Cristiane Morais Smith, Wiel H. Evers, Guy Allan, Thomas Altantzis, Sara Bals, Daniel Vanmaekelbergh

The interest in 2-dimensional systems with a honeycomb lattice and related Dirac-type electronic bands has exceeded the prototype graphene. We show that atomically coherent honeycomb superlattices of rocksalt (PbSe, PbTe) and zincblende (CdSe, CdTe) semiconductors can be obtained by nanocrystal...
