DC, RF and noise performance of InAs/AlSb HEMTs with in situ CVD SiNx-film for early-protection against oxidation

Giuseppe Moschetti, Eric Lefebvre, Martin Fagerlind, Per-Åk Nilsson, L. Desplanque, Xavier Wallart, Jan Grahn

A new method for avoiding air exposure of the mesa-floor during processing of shallow-mesa InAs/AlSb HEMTs is reported. The method is based on the in situ chemical vapor deposition (CVD) of a SiNx-film, right after the shallow-mesa dry-etch process. The in situ CVD method allows also growing a…

Scanning Gate Spectroscopy of transport across a Quantum Hall Nano-Island

F. Martins, S. Faniel, B. Rosenow, M. G. Pala, Hermann Sellier, Serge Huant, L. Desplanque, X. Wallart, Vincent Bayot, B. Hackens

We explore transport across an ultra-small Quantum Hall Island (QHI) formed by closed quan- tum Hall edge states and connected to propagating edge channels through tunnel barriers. Scanning gate microscopy and scanning gate spectroscopy are used to first localize and then study a single QHI near a…

Detection of neurotoxic gases by functionalized silicon nanowire field-effect transistors

J.P. Simonato, L. Ordronneau, A. Carella, V. Passi, Emmanuel Dubois, S. Lenfant, Dominique Vuillaume

The threat of a chemical attack on homeland and military forces continues to grow and recent examples such as the terrorist attack of the Metro of Tokyo have clearly shown that organophosphorus agents (OPs) are powerful neurotoxic molecules that can actually be used as weapons of chemical terrorism…

Giant rotary power of a fishnet-like metamaterial

S.X. Wang, F. Garet, Eric Lheurette, M. Astic, J.L. Coutaz, D. Lippens

We show experimentally and numerically that cholesteric-type metal-dielectric structures, made of twisted sub-wavelength hole elliptical–shaped arrays, exhibit strong optical activity and circular dichroism. The experimental demonstration is carried out with terahertz time-domain spectroscopy…

Assisted Channel Estimation with Dynamic Allocation Pilot Subcarriers for OFDM Communications

Boudali Ouarzazi, Atika Rivenq, Iyad Dayoub, Marion Berbineau

In this paper, a transmission system based on OFDM (Orthogonal Frequency Division Multiplexing) technique and channel estimation is proposed. The idea is to enhance the assisted channel estimation without data rate loss. A solution based on frequency diversity is proposed. With the same number of…

Rotational temperatures in RF plasma of Ar-H2O mixtures at low and moderated pressure

Adriana Annusova, Jaroslav Krištof, Corinne Foissac, Pavel Veis, Philippe Supiot

An Ar-H2O discharge with Ar content from 0 to 95 % at 67 and 266 Pa have been studied by optical emission spectroscopy. The plasma was excited at 27 MHz by a helical cavity with a power set at 30 W. The rotational temperatures of N2(C3Πu) and OH(A2 Σ + ) emitters were determined through spectral…

Toward the understanding of the interfacial dairy fouling deposition and growth mechanisms at a stainless steel surface : a multiscale approach

M. Jimenez, Guillaume Delaplace, N. Nuns, S. Bellayer, D. Deresmes, G. Ronse, G. Alogaili, M. Collinet-Fressancourt, M. Traisnel

The microstructures of two dairy fouling deposits obtained at a stainless steel surface after different processing times in a pilot plate heat exchanger were investigated at different scales. Electron-Probe Micro Analysis, Time-of-Flight Secondary Ion Mass Spectrometry, Atomic Force Microscopy, and…

Open problems in mathematical modelling and physical experiments: exploring exponential function

Raffaele Pisano, Paolo Bussotti

Generally speaking the exponential function has large applications and it is used by many non physicians and non mathematicians, too. Nevertheless some crucial and practical problems happen for its mathematical understanding. Mostly, this part of mathematical cognitive programmes introduce it from…
