Influence of the electronic structure and the multi-exciton spectral density on the multiple exciton generation in semiconductor nanocrystals

Christophe Delerue, Guy Allan

Several experimental works have reported that a single high-energy photon could generate multiple excitons in semiconductor nanocrystals and several theories have been proposed to explain these results. Using a tight-binding method, we calculate the electronic structure of InAs, Si, and PbSe…

Nonlinear based Time Reversal acoustic applied to crack detection: Simulations and experiments

T. Goursolle, S. dos Santos, Olivier Bou Matar, S. Callé

In nondestructive evaluation, Nonlinear Elastic Wave Spectroscopy (NEWS) methods represent powerful tools to explore damaged zones in a sample. The combination of these methods with Time Reversal (TR) process can be used to either increase the stress on the retrofocusing position or to retrofocuse…

Electronic Scheme for Multiplexed Dynamic Behavior Excitation and Detection of Piezoelectric Silicon-Based Micromembranes

Cédric Ayela, Thomas Alava, Denis Lagrange, Denis Remiens, Caroline Soyer, Thierry Ondarçuhu, Anders Greve, Liviu Nicu

A new concept for a precise compensation of the static capacitance of piezoelectric silicon-based micromembranes is proposed. Combining analog and digital field-programmable gate array hardware elements with specific software treatment, this system enables the parallel excitation and detection of…

Influence of the surface termination on the electrochemical properties of boron-doped diamond (BDD) interfaces

Paolo Actis, Alain Denoyelle, Rabah Boukherroub, Sabine Szunerits

The paper reports on the electrochemical study of heavily boron-doped diamond (BDD) in aqueous media. Cyclic voltammetry and Mott-Schottky analysis were used to evaluate the influence of the surface termination on the electrochemical properties of BDD electrodes. The behavior of aminated BDD (NH…

Electroactive Nanorods and Nanorings Designed by Supramolecular Association of π-Conjugated Oligomers

Olivier J. Dautel, Mike Robitzer, Jean-Charles Flores, Denis Tondelier, Françoise Serein-Spirau, Jean-Pierre Lère-Porte, David Guérin, Stéphane Lenfant, Monique Tillard, Dominique Vuillaume, Joël J.E. Moreau

In investigations into the design and isolation of semiconducting nano-objects, the synthesis of a new bisureido -conjugated organogelator has been achieved. This oligo(phenylenethienylene) derivative was found to be capable of forming one-dimensional supramolecular assemblies, leading to the…

Gold nanoparticle-pentacene memory-transistors

Christophe Novembre, David Guérin, Kamal Lmimouni, Christian Gamrat, Dominique Vuillaume

We demonstrate an organic memory-transistor device based on a pentacene-gold nanoparticles active layer. Gold (Au) nanoparticles are immobilized on the gate dielectric (silicon dioxide) of a pentacene transistor by an amino-terminated self-assembled monolayer. Under the application of writing and…

Nonlinear effects in split ring resonators loaded with heterostructure barrier varactors

Jorge Carbonell, Vicente Boria, Didier Lippens

The advantages afforded by the symmetrical C(V) characteristics of Heterostructure Barrier Varactor (HBV) diodes for the fabrication of nonlinear metamaterials are investigated numerically. The studies are conducted by means of full-wave numerical modelling along with circuit analysis. It is…

Single Carbon Nanotube Transistor at GHz Frequency

Julien Chaste, Lorentz Lechner, Pascal Morfin, Gwendal Fève, Takis Kontos, Jean-Marc Berroir, D. Christian Glattli, Henri Happy, Perti Hakonen, Bernard Plaçais

We report on microwave operation of top-gated single carbon nanotube transistors. From transmission measurements in the 0.1-1.6 GHz range, we deduce device transconductance gm and gate-nanotube capacitance Cg of micro- and nanometric devices. A large and frequency-independent gm of about 20…
