Performance improvement with non-alloyed ohmic contacts technology on AlGaN/GaN High Electron Mobility Transistors on 6H-SiC substrate

Marie Lesecq, Yassine Fouzi, Ali Abboud, N. Defrance, Francois Vaurette, Saliha Ouendi, Etienne Okada, Marc Portail, Micka Bah, Daniel Alquier, Jean-Claude de Jaeger, Eric Frayssinet, Yvon Cordier

In this paper, non-alloyed ohmic contacts regrown by molecular beam epitaxy (MBE) are fabricated on AlGaN/ GaN high-electron-mobility transistors on 6H-SiC substrate. Low ohmic contact resistance of 0.13 Ω.mm is obtained. This paper demonstrates the high frequency and high power performance…

Precision of neuronal localization in 2D cell cultures by using high-performance electropolymerized microelectrode arrays correlated with optical imaging

Mahdi Ghazal, Corentin Scholaert, Corentin Dumortier, Camille Lefebvre, Nicolas Barois, Sebastien Janel, Mehmet Tarhan, Morvane Colin, Luc Buée, Sophie Halliez, Sébastien Pecqueur, Yannick Coffinier, F. Alibart, Pierre Yger

Recently, the development of electronic devices to extracellularly record the simultaneous electrical activities of numerous neurons has been blooming, opening new possibilities to interface and decode neuronal activity. In this work, we tested how the use of EDOT electropolymerization to tune post…

Genes Involved in miRNA Biogenesis Are Not Downregulated in SARS-CoV-2 Infection

Nathalie Garnier, Famara Sane, Layal Massara, Fabrice Soncin, Philippe Gosset, Didier Hober, Sabine Szunerits, Ilka Engelmann

miRNAs, small non-coding RNAs that regulate gene expression, are involved in various pathological processes, including viral infections. Virus infections may interfere with the miRNA pathway through the inhibition of genes involved in miRNA biogenesis. A reduction in the number and the levels of…

Development of nanomaterial enabling highly sensitive SALDI‐MS peptide analysis

Aline Cournut, Ioana Silvia Hosu, Flavie Braud, Paul Moustiez, Yannick Coffinier, Christine Enjalbal, Claudia Bich

RationaleSALDI-MS (Surface-Assisted Laser Desorption/Ionisation Mass Spectrometry) is an approach derived from MALDI-MS (Matrix-Assisted Laser Desorption/Ionisation) which overcomes the drawbacks associated with the use of organic matrices required to co-crystallize with the analytes. Indeed,…

Nanoscale electronic transport at graphene/pentacene van der Waals interface

Michel Daher Mansour, Jacopo Oswald, Davide Beretta, Michael Stiefe, Roman Furrer, Michel Calame, Dominique Vuillaume

We report a study on the relationship between structure and electron transport properties of nanoscale graphene/pentacene interfaces. We fabricated graphene/pentacene interfaces from 10-30 nm thick needle-like pentacene nanostructures down to two-three layers (2L-3L) dendritic pentacene islands,…

Epitaxial La0.5Sr0.5MnO3‐δ Bipolar Memristive Devices with Tunable and Stable Multilevel States

Carlos Moncasi, Gauthier Lefèvre, Quentin Villeger, Laetitia Rapenne, Thoai‐khanh Khuu, Fabrice Wilhelm, Andrei Rogalev, Carmen Jiménez, Mónica Burriel

Valence change memories are novel data storage devices in which the resistance is determined by a reversible redox reaction triggered by voltage. The oxygen content and mobility within the active materials of these devices play a crucial role in their performance. Therefore, materials which present…
