Influence of electronic structure and multiexciton spectral density on multiple-exciton generation in semiconductor nanocrystals : tight-binding calculations

Guy Allan, Christophe Delerue

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…

Magnitude modulation of microwave signals by ultrafast control of membrane LT-GaAs photo switching devices

Charlotte Tripon-Canseliet, Salim Faci, Georges Alquié, Karine Blary, Stéphane Formont, Jean Chazelas

Microwave photonics contributes through ultrafast devices to the processing of high data rates. In this area, microwave photoconductive switches (MPCSs) in integrated technology have proved their performances to control the transmission of high frequency signals in complex systems. A description of…

Gold nanoparticle-pentacene memory-transistors

C. Novembre, David Guérin, K. Lmimouni, C. Gamrat, D. 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 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…

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…
