Selective GaN sublimation and local area regrowth for co-integration of enhancement mode and depletion mode Al(Ga)N/GaN high electron mobility transistors

Thi Huong Ngo, Rémi Comyn, Sébastien Chenot, Julien Brault, Benjamin Damilano, Stéphane Vézian, Eric Frayssinet, Flavien Cozette, Christophe Rodriguez, Nicolas Defrance, François Lecourt, Nathalie Labat, Hassan Maher, Yvon Cordier

In this paper, we report on the fabrication of a normally-off Al(Ga)N/GaN high electron mobility transistor with selective area sublimation under vacuum of the p type doped GaN cap layer. This soft method makes it possible to avoid damages otherwise induced by post processing with reactive ion…

Thermoelectric properties of nanostructured porous-polysilicon thin films

Katir Ziouche, Ibrahim Bel-Hadj, Zahia Bougrioua

In this paper, we address the optimization of the electrical and thermoelectrical properties of nanostructured polysilicon material for integration in thermoelectric (TE) devices. In particular, we describe an original method to build a superficial and nanostructured porous polysilicon (POpSi) thin…

2DEG transport properties over temperature for AlGaN/GaN HEMT and AlGaN/InGaN/GaN pHEMT

Md. Abdul Kaium Khan, Mohammad Abdul Alim, Christophe Gaquière

For the commercial implementation of GaN-based high electron mobility transistor (HEMT) and GaN-based pseudomorphic HEMT (pHEMT), the temperature dependency of the two-dimensional electron gas (2DEG) is crucial. Herein, the temperature dependency of 2DEG for AlGaN/GaN HEMT and AlGaN/InGaN/GaN pHEMT…

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…

Effect of In0.70Ga0.30As quantum dot insertion in the middle cell of InyGa1-yP/InxGa1-xAs/Ge triple-junction for solar cells

Abdelkader Aissat, Said Nacer, Jean-Pierre Vilcot

This paper focuses on the simulation and optimization of electrical and structural properties of high efficiency InGaP/InGaAs/Ge triple junction solar cells that incorporate In0.7Ga0.3As quantum dots with in the GaAs middle cell material. Current density-voltage (J-V), external quantum efficiency (…

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.…
