Surface asymmetry of coated spherical nanoparticles

Amélie H.R. Koch, Gaëtan Lévêque, Sebastian Harms, Karmena Jaskiewicz, Max Bernhardt, Andreas Henkel, Carsten Sönnichsen, Katharina Landfester, George Fytas

We validate the nonspherical grafting arrangement of isotropically coated spherical nanoparticles as very recently proposed. We utilize localized surface plasmon resonance enhanced dynamic polarized and depolarized light scattering from Au nanoparticles, the spherical symmetry of which was revealed…

Epitaxial Bi2Sr2Co2Oy thin films as a promising p-type transparent conducting oxides

Shufang Wang, Liqing Sun, Hongrui Zhang, El Hadj Dogheche, Jianglong Wang, Guangsheng Fu

Transparent conductive p-type Bi2Sr2Co2Oy thin films were epitaxial grown on LaAlO3 substrate by pulsed laser deposition. Film with thickness of 50 nm showed a room temperature resistivity of about 5.5 mΩ cm and an average optical transmittance of about 51% in the visible region, resulting in a…

Multipath component distance-based fingerprinting technique for non-cooperative outdoor localization in NLOS scenarios

Isabelle Vin, Davy Gaillot, Pierre Laly, M. Lienard, Pierre Degauque

Accurate localization of mobile phone users is needed for search and rescue applications or for electronic surveillance in urban or suburban areas. Assuming that the mobile station (MS) has been roughly localized by the cellular network or by any other means, we propose an approach using dedicated…

Threshold voltage study of scaled self-aligned In0.53Ga0.47As metal oxide semiconductor field effect transistor for different source/drain doping concentrations

A. Dehzangi, M.F. Mohd Razip Wee, Nicolas Wichmann, S. Bollaert, M.R. Buyong, B.Y. Majlis

A multi-gate n-type In0.53Ga0.47As metal oxide semiconductor field effect transistor is fabricated using the gate first self-aligned method and air-bridge technology with an 8 nm thick Al2O3 oxide layer. By scaling the gate length down to 200 nm, the effect of two different source/drain doping…

Interferometer-based microwave microscopy operating in transmission mode

Kamel Haddadi, Tuami Lasri

A microwave near-field sensing technique with sub-wavelength resolution is proposed for nondestructive local characterization of materials. The method is based on the measurement of a transmission coefficient by means of an association of a vector network analyzer, a hybrid coupler, an evanescent…

Silicon-microtube scaffold decorated with anatase TiO2 as a negative electrode for a 3D litium-ion microbattery

Etienne Eustache, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Gilles Patriarche, David Troadec, Nathalie Rolland, Thierry Brousse, Christophe Lethien

An optimized scaffold based on silicon microtubes is designed to increase the surface capacity of 3D lithium-ion microbatteries. High-depth, mechanically robust microstructures are fabricated using microelectronic facilities. Conformal deposition of anatase TiO2 is achieved using atomic layer…

Gold-free ternary III-V antimonide nanowire arrays on silicon : twin-free down to the first bilayer

Sònia Conesa-Boj, Dominik Kriegner, Xiang-Lei Han, S.R. Plissard, Xavier Wallart, Julian Stangl, Anna Fontcuberta I Morral, Philippe Caroff

With the continued maturation of III-V nanowire research, expectations of material quality should be concomitantly raised. Ideally, III-V nanowires integrated on silicon should be entirely free of extended planar defects such as twins, stacking faults, or polytypism, position-controlled for…

A modal formulation for the propagation of guided waves in straight and curved pipes and the scattering at their junction

M. El Bakkali, A. Lhémery, V. Baronian, Sébastien Grondel

The well-established semi-analytic finite element (SAFE) method for predicting guided wave propagation in straight guides is extended to deal with curved pipes using curvilinear coordinates system, following developments by Treyssède and Laguerre [J. Sound Vib. 329 1702-16 (2010)] for helical wires…

Sub-THz characterisation of monolayer graphene

Ehsan Dadrasnia, Sujitha Puthukodan, Vinod V. K. Thalakkatukalathil, Horacio Lamela, Guillaume Ducournau, Jean-Francois Lampin, Frédéric Garet, Jean-Louis Coutaz

We explore the optical and electrical characteristics of monolayer graphene by using pulsed optoelectronic terahertz time-domain spectroscopy in the frequency range of 325-500 GHz based on fast direct measurements of phase and amplitude. We also show that these parameters can, however, be measured…
