On the origin of increased sensitivity and mass resolution using silicon masks in MALDI

Laurent Diologent, Julien Franck, Maxence Wisztorski, A. Treizebre, Cristian Focsa, Isabelle Fournier, Michael Ziskind

Since its development, MALDI has proved its performance in the analysis of intact biomolecules up to high molecular weights, regardless of their polarity. Sensitivity of MALDI instruments is a key point for breaking the limits of observing biomolecules of lower abundances. Instrumentation is one...

Comparison of shallow-mesa InAs/AlSb HEMTs with and without early-protection for long-term stability against Al(Ga)Sb oxidation

E. Lefebvre, G. Moschetti, M. Malmkvist, L. Desplanque, X. Wallart, J. Grahn

The fabrication process of InAs/AlSb high electron mobility transistors (HEMTs) has been improved by depositing, after the shallow-mesa isolation of the active area, a thin SiNx-film on the exposed AlGaSb mesa floor. Devices with and without this early-protection against Al(Ga)Sb oxidation have...

High polarization high breakdown voltage AlN/GaN-on-silicon transistors

Nicolas Herbecq, Isabelle Roch-Jeune, F Medjdoub

We have developed a back-side process on AlN/GaN-on-Si DHFETs in order to drastically enhance their electrical performances. With a buffer thickness of 1.8 μm, the Si substrate has been locally etched up to the buffer layers between the drain and the gate. After local silicon removal, the three-...

Bandwidth enhancement in disordered metamaterial absorbers

Jianping Hao, Eric Lheurette, Ludovic Burgnies, Etienne Okada, Didier Lippens

In this letter, we show numerically and experimentally that a positional disorder of a collection of absorbing electromagnetic wave resonators operating in the long wavelength regime dramatically enhances the absorption bandwidth. The demonstration is performed by using single-size ring-shaped thin...

Experimental demonstration of anomalous nonreciprocal optical response of 1D periodic magnetoplasmonic nanostructures

L. Halagacka, Mathias Vanwolleghem, Francois Vaurette, Jamal Ben Youssef, Philippe Gogol, N. Yam, K. Postava, B. Dagens, J. Pistora

In this paper we analyze the optical and transversal magnetooptical (MO) response of magnetoplasmonic (MP) nanostructures. The MP structure is a 1D periodic gold grating fabricated by lift-off technique on the MO dielectric substrate (Bi-substituted yttrium iron garnet BixY3−xFe5O12). Following our...

Multiuser phase coded costas signals with improved cross-correlation and partial cross-ambiguity properties

Nadjah Touati, Charles Tatkeu, Atika Rivenq, Thierry Chonavel

Costas codes are a variant of frequency hopping codes that achieve the «thumbtack» auto-ambiguity function needed in radar applications. However, they may show poor cross- ambiguity properties when selected and assigned randomly which makes them poorly adapted to multiuser radar applications. In...

Feasibility of a high bit rate power line communication between an inverter and a motor

Virginie Degardin, Khaled Kilani, Lamine Koné, M. Lienard, Pierre Degauque

In the aerospace domain, more electrical aircraft will have to face a drastic issue in the future, in relation to an increase in the number of wires and connectors, which impact weight and system reliability. A possible solution could be using power-line communications (PLC). In this paper, we...

Longitudinal and transversal polarization switching in strained ferroelectrics

Laurent Baudry, Igor A. Luk'Yanchuk, A. Razumnaya

Using the multicomponent Landau-Devonshire functional we study the field-induced polarization switching in c-oriented ferroelectric phase of epitaxial perovskite film and found that two different regimes are possible: (i) longitudinal switching with change of the polarization modulus and (ii)...

Integrated measurement platform for thermal conductivity measurements in thin-film crystalline silicon and silicon-germanium

Maciej Haras, Valeria Lacatena, Stéphane Monfray, J.F. Robillard, Thomas Skotnicki, Emmanuel Dubois

Thermoelectric conversion requires materials with low thermal conductivity k high electrical conductivity s and thermopower P. Performance of thermoelectric material is evaluated by the zT=P^2sT/k figure-of-merit. Bi2Te3 or Sb2Te3 are usually used near room temperature but they are harmful,...
