GaN-on-silicon transistors with reduced current collapse and improved blocking voltage by means of local substrate removal

Idriss Abid, Eleonora Canato, Matteo Meneghini, Gaudenzio Meneghesso, Kai Cheng, F Medjdoub

We report on the demonstration of low trapping effects above 1200 V of GaN-on-silicon transistors using a local substrate removal (LSR) followed by a thick backside ultra-wide-bandgap AlN deposition. Substrate ramp measurements show reduced hysteresis up to 3000 V. It has been found that the LSR…

Anti-biofilm activity of dodecyltrimethylammonium chloride microcapsules against Salmonella enterica serovar Enteritidis and Staphylococcus aureus

Simon Khelissa, Adem Gharsallaoui, Jian Wang, Emilie Dumas, Alexandre Barras, Charafeddine Jama, Fouzia Jbilou, Noureddine Loukili, Nour-Eddine Chihib

Dodecyltrimethylammonium chloride (DTAC) was trapped into maltodextrins/pectin spray dried microcapsules to improve its activity against Salmonella enteritidis and Staphylococcus aureus biofilms. Two different microcapsules were prepared: uncomplexed DTAC-microcapsules (UDM), containing DTAC and…

Intertrack surface losses in miniature coplanar waveguide on silicon-on-insulator

Jaouad Marzouk, Vanessa Avramovic, S. Arscott

Attenuation has been studied in different-sized coplanar waveguides (CPW) patterned onto silicon-on-insulator (SOI) for three different surfaces between the CPW tracks: a silicon dioxide/silicon interface, a hydrogen-terminated silicon surface, and a native oxide. For large-gap CPW (signal track…

Le cancer du pancréas est l’un des cancers les plus mortels avec un pronostic extrêmement sombre. En 2020, le taux de survie à 5 ans reste très faible (de 3 à 9 % seulement) et la médiane de survie est de moins de 6 mois. Malgré des progrès dans la prise en charge des patients, les thérapies…, Pancreatic cancer is one of the deadliest cancers with an extremely poor prognosis. In 2020, the 5-year survival rate remains very low (only 3 to 9%) and the median is less than 6 months. Despite significant progress in the patient care, current therapies do not have the expected effectiveness.…

The traditional transistor miniaturization is resulting in devices experiencing quantum effects. Rather than fighting these effect by developing new architectures of conventional silicon-based devices, the long-term solution might be in revisiting existing knowledge of these fundamental concepts…, La miniaturisation continue des composants électroniques a atteint un seuil au-delà duquel les effets quantiques deviendront prépondérants. Plutôt que de vouloir supprimer ces effets, il peut être intéressant de les mettre à profit. Mais ce changement de perspective nécessite d’avoir une…

Comparison of DC and RF Sputtering of ZnSnN₂ : Effect on Structural, Optical and Electrical Properties

Ngoc Kim Thanh Bui, Mathieu Halbwax, Jean-Pierre Vilcot

Thin-film PV technology was initially used as a low raw material consumption, so a low cost, technology. Amorphous Si was firstly used; it effectively led to a low cost technology but also a low efficiency one. CdTe, and more recently copper indium gallium di-selenide (CIGS), materials were then…
