Comparison of shallow-mesa InAs/AlSb HEMTs with and without early-protection for long-term stability against Al(Ga)Sb oxidation

E. Lefebvre, G. Moschetti, M. Malmkvist, L. Desplanque, X. Wallart, J. Grahn

The fabrication process of InAs/AlSb high electron mobility transistors (HEMTs) has been improved by depositing, after the shallow-mesa isolation of the active area, a thin SiNx-film on the exposed AlGaSb mesa floor. Devices with and without this early-protection against Al(Ga)Sb oxidation have…

Optical properties of nanoporous gallium nitride for photonic applications

Bandar Alshehri

The aim of this research is to characterize the optical properties of a gallium nitride thin film grown on sapphire by MOCVD. Nanoporous of gallium nitride are formed by electrochemical etching. Refractive index, thickness and birefringence are extracted from the nanoporous thin film. Prism…

Effects of Enhanced Image Quality in Infrastructure Monitoring through Micro Aerial Vehicle Stabilization

Chung-Hsin Kuo, Sébastien Kanlanjan, Louis Pagès, Hanadi Menzel, Sascha Power, Chen-Ming Kuo, Christian Boller, Sébastien Grondel

Traditional monitoring of large infrastructure such as towers of churches or for cooling, chimneys or any other type of tall buildings can require extreme effort and hence become very risky and costly since it mainly requires people to be moved around. An interesting alternative in that regard is…

Continuous microcarrier-based cell culture in a benchtop microfluidic bioreactor

Fabien Abeille, Frédérique Mittler, Patricia Obeïd, Maxime Huet, Frédérique Kermarrec, Monika Dolega, Fabrice P. Navarro, Patrick Pouteau, Beatrice Icard, Xavier Gidrol, Vincent Agache, Nathalie Picollet-D’hahan

Microfluidic bioreactors are expected to impact cell therapy and biopharmaceutical production due to their ability to control cellular microenvironments. This work presents a novel approach for continuous cell culture in a microfluidic system. Microcarriers (i.e., microbeads) are used as growth…

Experimental demonstration of anomalous nonreciprocal optical response of 1D periodic magnetoplasmonic nanostructures

L. Halagacka, Mathias Vanwolleghem, Francois Vaurette, Jamal Ben Youssef, Philippe Gogol, N. Yam, K. Postava, B. Dagens, J. Pistora

In this paper we analyze the optical and transversal magnetooptical (MO) response of magnetoplasmonic (MP) nanostructures. The MP structure is a 1D periodic gold grating fabricated by lift-off technique on the MO dielectric substrate (Bi-substituted yttrium iron garnet BixY3−xFe5O12). Following our…

Surface acoustic wave bandgaps for conical pillars on a piezoelectric substrate

Abdelali Mrabti, Mourad Oudich, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani, Abdelkrim Talbi, Jérémy Streque, Yu Du, Ali Soltani, Philippe Pernod

We report theoretically on the band structure of a square lattice phononic crystal made up of nickel (Ni) conical pillars deposited on the surface of a semi-infinite LiNbO3 substrate. Calculations have been performed with a 3D finite element method taking into account material anisotropy and…

Back-gated microwave field-effect transistors based on transferred CVD-grown graphene

Wei Wei, Mohamed Moez Belhaj, Geetanjali Deokar, D. Mele, Emiliano Pallecchi, Emmanuelle Pichonat, Dominique Vignaud, Henri Happy

Graphene based transistors have drawn growing interest from both industries and Laboratories [1-3]. In this work, we present both fabrication process and characterization of graphene field-effect transistors. Large scale monolayer graphene was grown by chemical vapor deposition (CVD) on Cu foils…

Key parameters of silicon micropillar arrays for solar cell performance optimization

Di Zhou, Yan Pennec, Bahram Djafari-Rouhani, Odile Cristini, Tao Xu, Yannick Lambert, Didier Stiévenard

Surface nanostructuration is an important challenge for the optimization of light trapping design in solar cell. We present simulations of the optical properties and efficiency of nanostructured (micropilars-MPs- or nanocones-NCs-) silicon based solar cells as well as measurements of their optical…
