0.2-μm InP/GaAsSb DHBT power performance with 10 mW/μm² and 25% PAE at 94 GHz

Mohammed Zaknoune, Etienne Okada, Estelle Mairiaux, Yannick Roelens, Damien Ducatteau, Peter Frijlink, Marc Rocchi, Hassan Maher

We report a 94-GHz large-signal load-pull characterization of InP/GaAsSb double heterojunction bipolar transistors. The investigated devices have an emitter area of 0.20 × 9.5 μm2. Biased for highest power added efficiency (PAE), an output power of 6.62 mW/μm2 (11 dBm), a power gain of 5.2 dB, 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…

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…

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…

Polymer based flapping-wing robotic insect : progress in design, fabrication and characterization

Alexandre Bontemps, Thomas Vanneste, Caroline Soyer, Jean-Bernard Paquet, Sébastien Grondel, Eric Cattan

In the last decade, many researchers pursued the development of tiny flying robots inspired by natural flyers destined for the exploration of confined spaces, for example. Within this context, our main objective is to devise a flying robot bioinspired from insect in terms of size and wing…

Electrical characterization of semiconductor nanowires by scanning tunneling microscopy

Corentin Durand, Pierre Capiod, Maxime Berthe, Tao Xu, Jean-Philippe Nys, Renaud Leturcq, Philippe Caroff, B. Grandidier

In order to understand the structural and electronic properties of semiconductor nanowires, scanning tunneling microscopy is an appealing technique that can supplement transmission electron microscopies and conventional electrical characterization techniques. It is able to probe the surface of…

Synthesis and characterization of BNT thin films

Sara Abou Dargham, Jihane Jabbour, Youssef Zaatar, Jamal Assaad, Antonio Khoury, Denis Remiens, Doumit Zaouk

Polycrystalline piezoelectric lead-free Bi0.5Na0.5TiO3 (abbreviated as BNT) thin films were deposited on glass substrates by an optimized Sol-Gel process using the Electrospray technique. X-ray Diffraction (XRD) analysis showed that after heating the films at 650˚C for 1 hour, dense and well…
