40 GSPS All Optical ADC with ENOB of 6.6 using EO Polymer Optical Deflector and Spatial Quantizer

Massinissa Hadjloum, Mohammed El Gibari, Mathieu Halbwax, Jean-Pierre Vilcot, Hong Wu Li, Afshin S. Daryoush

40GSPS analog-to-digital converters (ADC) are required for realization of digital receivers up to 20GHz. An all optical ADC is presented using an optical deflector for spatial sampling. The optimized design of optical deflector is based on optical beam propagation and finite element modeling…

Acoustic Characterization of Patterning Degradation during Wet Etching

Christophe Virgilio, Philippe Garnier, Mathieu Foucaud, Arnaud Devos, David Pinceau, Julien Carlier, Pierre Campistron, Bertrand Nongaillard, Marc Neyens, Lucile Broussous

Photoresist degradation can occur during wet etching processes due to chemicals diffusion through the polymer. The adhesion of the resist is not guaranteed anymore and damage on the resist / material interface appears. This phenomenon is usually monitored by optical methods. However, invisible…

High charge mobility in two-dimensional percolative networks of PbSe quantum dots connected by atomic bonds

Wiel Evers, Juleon Schins, Michiel Aerts, Aditya Kulkarni, Pierre Capiod, Maxime Berthe, B. Grandidier, Christophe Delerue, Herre van Der Zant, Carlo van Overbeek, Joep Peters, Daniel Vanmaekelbergh, Laurens Siebbeles

Two-dimensional networks of quantum dots connected by atomic bonds have an electronic structure that is distinct from that of arrays of quantum dots coupled by ligand molecules. We prepared atomically coherent two-dimensional percolative networks of PbSe quantum dots connected via atomic bonds.…

MnO 2 Thin Films on 3D Scaffold: Microsupercapacitor Electrodes Competing with “Bulk” Carbon Electrodes

Etienne Eustache, Camille Douard, Richard Retoux, Christophe Lethien, Thierry Brousse

A simple, binder-free fabrication of high capacitance electrodes based on manganese dioxide (MnO2) thin films is reported. The 3D structure of these electrodes significantly improves the areal capacitance of the MnO2 thin films up to 670 mF cm−2 in aqueous electrolyte, which is 4.5 times higher…

Analysis and optimization of a piezoelectric harvester on a car damper

Barbara Lafarge, Christophe Delebarre, Sébastien Grondel, Octavian Curea, Amélie Hacala-Perret

Low power levels obtained from piezoelectric conversion of ambient vibrations appear to be a promising solution to supply wireless sensors embedded inside automotive suspension. However such a solution requires overall an optimum power extraction from the piezoelectric power harvester. This leads…

GaN-on-silicon high electron mobility transistors with blocking voltage of 3 kV

Malek Zegaoui, Nicolas Herbecq, Astrid Linge, B. Grimbert, F Medjdoub, I. Roch-Jeune

A three-terminal breakdown voltage over 3 kV is reported on AlGaN/GaN high-electron-mobility transistors (HEMTs) grown on silicon (Si) (111) substrate with a buffer thickness of 5.5 μm. The breakdown voltage of the 1.5 × 50 μm2 devices has been improved by more than 200% by applying a local…
