Electronic transport mechanisms in scaled gate-all-around silicon nanowire transistor arrays

N. Clement, X.L. Han, Guilhem Larrieu

Low-frequency noise is used to study the electronic transport in arrays of 14 nm gate length vertical silicon nanowire devices. We demonstrate that, even at such scaling, the electrostatic control of the gate-all-around is sufficient in the sub-threshold voltage region to confine charges in the...

Progressive multi-layer drop-casting of CdSe nanoparticles for photocurrent down shifing monitoring

Yannick Lambert, Di Zhou, Tao Xu, Odile Cristini, D. Deresmes, B. Grandidier, D. Stievenard

We investigated the spectroscopic photocurrent response of photovoltaic devices versus an increasing number of drop-casted CdSe nanoparticles onto planar and nanocones silicon p-i-n junctions. For all samples, a strong enhancement of the photocurrent in the UV range was detected as well as a...

High spectral purity microwave and terahertz oscillator

Gwennaël Danion, Goulc'Hen Loas, Ludovic Frein, Cyril Hamel, Anthony Carré, Steve Bouhier, Marc Vallet, Marc Brunel, Antoine Rolland, Mehdi Alouini, François Bondu, Alexandre Beck, Guillaume Ducournau, Mohamed Zaknoune, Christophe Coinon, Xavier Wallart, Emilien Peytavit, Tahsin Akalin, Jean-Francois Lampin, Frédéric Cleva, Jean-Pierre Coulon, Mourad Merzougui, Alain Brillet, Gregoire Pillet, Loïc Morvan, Ghaya Baili, Jérôme Bourderionnet

We report on the design of an ultra stable microwave/THz oscillator and on the realization and the characterization of its laser source. The tunable oscillator is expected to show below -150 dB rad2/Hz phase instability at an offset frequency of 10 kHz for a 30 GHz carrier frequency, as well as 18...

The Faraday threshold in small cylinders and the sidewall non-ideality

William R. Batson, Farzam Zoueshtiagh, Raviprasad Narayanan

In this work we investigate, by way of experiments and theory, the Faraday instability threshold in cylinders at low frequencies. This implies large wavelengths where effects from mode discretization cannot be ignored. Careful selection of the working fluids has resulted in an immiscible interface...

Spatial terahertz modulator

Zhenwei Xie, Xinke Wang, Jiasheng Ye, Shengfei Feng, Wenfeng Sun, Tahsin Akalin, Yan Zhang

Terahertz (THz) technology is a developing and promising candidate for biological imaging, security inspection and communications, due to the low photon energy, the high transparency and the broad band properties of the THz radiation1,2,3. However, a major encountered bottleneck is lack of...

Surface plasmons in coaxial metamaterial cables

M.S. Kushwaha, Bahram Djafari-Rouhani

Thanks to Victor Veselago for his hypothesis of negative index of refraction, metamaterials – engineered composites – can be designed to have properties difficult or impossible to find in nature: they can have both electrical permitivity (ǫ) and magnetic permeability (µ) simultaneously negative....

Time-reversal UWB positioning beacon for railway application

B. Fall, F. Elbahhar, M. Heddebaut, Atika Rivenq

This paper studies a new positioning beacon for railway transport using Ultra Wideband (UWB) radio and Time Reversal (TR) techniques. UWB radio has the potential to offer a good level of performance in terms of localization accuracy. Time Reversal channel pre-filtering facilitates signal detection...

Deterministic placement of doping atoms on hydroxylated surfaces

L. Mathey, L. Veyre, H. Fontaine, V. Enyedi, K. Yckache, J. Guerrero, N. Chevalier, F. Martin, J.P. Barnes, F. Bertin, C. Durand, Maxime Berthe, B. Grandidier, C. Thieuleux, C. Coperet

An improved approach of semi-conductor doping by Molecular Layer Deposition (MLD) is investigated. Here, dopant-containing molecules are directly grafted onto silica-coated silicon wafers and optimized ligands can provide more effective dopant drive-in annealing. The grafting approach is validated...
