A New Photomechanical Molecular Switch Based on a Linear π-Conjugated System

Stéphane Lenfant, Yannick Viero, Christophe Krzeminski, Dominique Vuillaume, Dora Demeter, I. L. Dobra, Maiténa Oçafrain, Philippe Blanchard, Jean Roncali, C. van Dick, Jérôme Cornil

We report the electron-transport properties of a new photoaddressable molecular switch. The switching process relies on a new concept based on linear π-conjugated dynamic systems, in which the geometry and, hence, the electronic properties of an oligothiophene chain can be reversibly modified by…

Impact of Gate Drain Spacing on Low-Frequency Noise Performance of In Situ SiN Passivated InAlGaN/GaN MIS-HEMTs

Mehdi Rzin, Jean-Marc Routoure, Bruno Guillet, Laurence Méchin, Magali Morales, Cédric Lacam, Piero Gamarra, Pierre Ruterana, F Medjdoub

In this paper we investigated the gate–drain access region spacing (L GD) effect on electrical and noise performance of InAlGaN/GaN metal– insulator–semiconductor high electron mobility transistors (MIS-HEMTs) using in situ SiN cap layer as gate insulator. Different L GD of InAlGaN/GaN MIS-HEMTs…

Zero echo time MRI- only treatment planning for radiation therapy of brain tumors after resection

C. Boydev, B. Demol, David Pasquier, Hervé Saint-Jalmes, G. Delpon, N. Reynaert

Using magnetic resonance imaging (MRI) as the sole imaging modality for patient modeling in radiation therapy (RT) is a challenging task due to the need to derive electron density information from MRI and construct a so-called pseudo-computed tomography (pCT) image. We have previously published a…

High Frequency Acoustic On-Chip Integration for Particle Characterization and Manipulation in Microfluidics

Sizhe Li, Julien Carlier, Malika Toubal, Huiqin Liu, Pierre Campistron, Dorothee Callens, Georges Nassar, Bertrand Nongaillard, Shishang Guo

This letter presents a microfluidic device that integrates high frequency (650 MHz) bulk acoustic waves for the realization of particle handling on-chip. The core structure of the microfluidic chip is made up of a confocal lens, a vertical reflection wall, and a ZnO film transducer coupled with a…

Complexity of the hot carrier relaxation in Si nanowires compared to bulk

Jing Li, Yann-Michel Niquet, Christophe Delerue

We investigate the relaxation of hot carriers by emission of phonons in bulk Si and Si nanowires (NWs) with an identical atomistic methodology. The phonon scattering is strongly enhanced in NWs. At high excitation energy, the carrier cooling is faster in NWs than in bulk, mainly due to the coupling…

A 4-fJ/spike artificial neuron in 65 nm CMOS technology

Ilias Sourikopoulos, Sara Hedayat, Christophe Loyez, Francois Danneville, Virginie Hoel, Eric Mercier, A. Cappy

As Moore's law reaches its end, traditional computing technology based on the Von Neumann architecture is facing fundamental limits. Among them is poor energy efficiency. This situation motivates the investigation of different processing information paradigms, such as the use of spiking neural…

Energy Consumption Models For MISO-UWB and TR-MISO-UWB Systems

Adil El Abboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

this paper, an energy consumption model is developed and exploited to evaluate the electrical energy consumption of ultra-wideband impulse radio (UWB-IR) systems. We develop the energy consumption models and our comparative study, on the one hand, for a system based single-input singleoutput (SISO…
