The Effects of AlN and Copper Back Side Deposition on the Performance of Etched Back GaN/Si HEMTs

Georges Pavlidis, Samuel Kim, Idriss Abid, Malek Zegaoui, F Medjdoub, Samuel Graham

The breakdown voltage of GaN/Si high electron mobility transistors (HEMTs) for power electronics has shown to be improved by removing the silicon substrate. The drawback to this approach is the increase in the device's thermal resistance which limits the power dissipation that the device can…

Micro-Electro-Mechanical-Systems advances for measurements at small scales: the vertical silicon probes technology extended to nearfield optics

B. Walter, E. Mairiaux, Sophie Eliet, Jean-Francois Lampin, Marc Faucher

Instrumentation intending to go beyond the limits of current Atomic Force Microscope setups (AFM), and applications requiring AFM to be integrated in non-standards environmental conditions need sensors that overcome limitations given by available probes. We show that the vertical probe technology…

Intrinsic transport properties of nanoporous graphene highly suitable for complementary field-effect transistors

Jing Li, Christophe Delerue

The recent success to synthesize an ordered array of pores in graphene by a bottom-up approach (Moreno et al 2018 Science 360 199) yields a semiconducting nanoporous graphene with a bandgap of 0.6 eV. In this paper, we present calculations of the intrinsic carrier mobility in this new type of two-…

Toxicity Effect of Silver Nanoparticles on Photosynthetic Pigment Content, Growth, ROS Production and Ultrastructural Changes of Microalgae Chlorella vulgaris

Layla Hazeem, Gamze Kuku, Etienne Dewailly, Christian Slomianny, Alexandre Barras, Abderrahmane Hamdi, Rabah Boukherroub, Mustafa Culha, Mohamed Bououdina

Silver nanoparticles (Ag NPs) exhibit antibacterial activity and are extensively used in numerous applications. The aim of this study was to examine the toxic effect of Ag NPs on the marine microalga, Chlorella vulgaris. The microalgae, at the exponential growth phase, were treated with different…

Broadband vibrational energy harvesting with a spherical piezoelectric transducer devoted to underwater wireless sensor networks

Daher Diab, Nikolay Smagin, Fabrice Lefebvre, Georges Nassar, Samih Isber, Fawaz El Omar, Adnan Naja

A new sensing node container based on a spherical piezoelectric transducer is proposed. This device provides broadband vibrational energy harvesting and sensing facilities intended for underwater wireless sensor networks. The transducer is composed of two acrylic glass (PMMA) half-spherical shells…

Monitoring cleaning cycles of fouled ducts using ultrasonic coda wave interferometry (CWI)

Bowei Chen, Dorothée Debavelaere-Callens, Pierre Campistron, Emmanuel Moulin, Pascal Debreyne, Guillaume Delaplace

Fouling in heat exchangers is the buildup of deposits on the solid surfaces. These deposits reduce the eco-efficiency of the processing equipment and increase the risk of subsequent surface contamination with the formation of biofilms. In the agro-food and water supplier sectors, which are our main…

ZnO/Carbon nanowalls shell/core nanostructures as electrodes for supercapacitors

Abdelouadoud Guerra, Amine Achour, Sorin Vizireanu, Gheorghe Dinescu, Samira Messaci, Toufik Hadjersi, Rabah Boukherroub, Yannick Coffinier, Jean-Jacques Pireaux

In this work, carbon nanowalls (CNW) were coated with zinc oxide (ZnO) for use as supercapacitor electrodes. The ZnO layers of different thicknesses were deposited using pulsed laser ablation in oxygen reactive atmosphere. The performance of the CNW-ZnO electrodes was found to be dependent on the…
