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...

Planning the electron traffic in semiconductor networks: A mesoscopic analog of the Braess paradox encountered in road networks

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

By combining quantum simulations of electron transport and scanning-gate microscopy, we have shown that the current transmitted through a semiconductor two-path rectangular network in the ballistic and coherent regimes of transport can be paradoxically degraded by adding a third path to the network...

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...

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...

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...

Stochastic magnetization dynamics in single domain particles

S. Giordano, Yannick Dusch, Nicolas Tiercelin, Philippe Pernod, Vladimir Preobrazhensky

Magnetic particles are largely utilized in several applications ranging from magnetorheological fluids to bioscience and from nanothechnology to memories or logic devices. The behavior of each single particle at finite temperature (under thermal stochastic fluctuations) plays a central role in...

Stress-mediated magnetoelectric memory effect with uni-axial TbCo2/FeCo multilayer on 011-cut PMN-PT ferroelectric relaxor

Yannick Dusch, Nicolas Tiercelin, A. Klimov, S. Giordano, Vladimir Preobrazhensky, Philippe Pernod

We present here the implementation of a magnetoelectric memory with a voltage driven writing method using a ferroelectric relaxor substrate. The memory point consists of a magnetoelastic element in which two orthogonal stable magnetic states are defined by combining uni-axial anisotropy together...
