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…

Estimation of parameters of heterogeneous concrete by non-contact method of surface waves : studies of role of frequency range

Radoslaw Drelich, Mariusz Kaczmarek, Bogdan Piwakowski

This work is devoted to study of the influence of selection of frequency range of dispersion curve of surface waves on estimation efficiency of shear wave velocities and thickness of inhomogeneous concrete cover. The non-contact ultrasonic method, signal processing and numerical optimization…

Anisotropic Swirling Surface Acoustic Waves from Inverse Filtering for On-Chip Generation of Acoustic Vortices

Antoine Riaud, Jean-Louis Thomas, Eric Charron, Adrien Bussonnière, Olivier Bou Matar, Michael Baudoin

From radio-electronics signal analysis to biological sample actuation, surface acoustic waves (SAWs) are involved in a multitude of modern devices. However, only the most simple standing or progressive waves such as plane and focused waves have been explored so far. In this paper, we expand the SAW…

Photo-hardenable and patternable PDMS/SU-8 hybrid functional material: A smart substrate for flexible systems

Rian Seghir, S. Arscott

The fabrication of flexible electronics and systems, using rigid and brittle materials directly produced on stretchable substrate, leads to some issues and incompatibilities. These include rigidity for processing and modular flexibility for applications, macroscopic flexibility, and local rigidity…
