Molecular beam epitaxial growth of 2D-boron nitride on Ni substrates

Jawad Hadid, Ivy Colambo, Jose Avila, Aexandre Plaud, Christophe Boyaval, D. Deresmes, Nicolas Nuns, Pavel Dudin, Annick Loiseau, Julien Barjon, Xavier Wallart, Dominique Vignaud

2D boron nitride (2D-BN) was synthesized by gas-source molecular beam epitaxy on Ni substrates using gaseous borazine and active nitrogen generated by a remote plasma source. Based on spatially resolved photoemission spectroscopy and on the detection of the π plasmon peak, we discuss the origin of…

Impact of forward body-biasing on ultra-low voltage switched-capacitor RF power amplifier in 28 nm FD-SOI

Guillaume Tochou, Andreia Cathelin, Antoine Frappé, Andreas Kaiser, Jan Rabaey

The Switched-Capacitor Power Amplifier (SCPA) has become a key enabler for modern wireless communication because of its high efficiency, high linearity, and high integrability. This paper discusses the impact of the extended Forward Body-Biasing (FBB) feature in 28 nm FD-SOI technology on Ultra-Low…

Unidirectional Coherent Phonon Emission in an Optomechanic Nanobeam Containing Coupled Cavities

Alexander Korovin, Yan Pennec, Bahram Djafari-Rouhani

Nonreciprocal phonon emission is predicted theoretically from the coherent excitation of two coupled optomechanical cavities arranged along a phoxonic crystal nanobeam. The latter consists of a periodic array of holes and stubs and exhibits simultaneous photonic and phononic bandgaps. It is shown…

A Comparative Study of the Whitening Methods in Linear Video Coding and Transmission Schemes

Hind Kanj, Anthony Trioux, François-Xavier Coudoux, M Gharbi, Patrick Corlay, Michel Kieffer

Linear Video Coding and Transmission (LVCT) schemes, pioneered by the SoftCast architecture, have been recently proposed as an alternative solution for wireless broadcast applications where users may experience severe channel quality fluctuations. LVCT schemes offer a graceful video quality…

Optimized ohmic contacts for InAlGaN/GaN HEMTs

Pierre Ruterana, Marie Pierre Chauvat, Magali Morales, Farid Medjdoub, Piero Gamarra, Christian Dua, Sylvain Delage

In this work, we have carried out a detailed transmission electron microscopy investigation on ohmic contacts in InAl GaN/GaN high electron mobility transistors consisting of Ti/Al/Ni/Au deposited by evaporation electron beam followed by a rapid thermal annealing at 875°C for 30s under N2…

Optomechanical Hot-Spots in Metallic Nanorod–Polymer Nanocomposites

Thomas Vasileiadis, Adnane Noual, Yuchen Wang, Bartlomiej Graczykowski, Bahram Djafari-Rouhani, Shu Yang, George Fytas

Plasmonic coupling between adjacent metallic nanoparticles can be exploited for acousto-plasmonics, single-molecule sensing, and photochemistry. Light absorption or electron probes can be used to study plasmons and their interactions, but their use is challenging for disordered systems and colloids…

Stiffening of nanoporous gold: experiment, simulation and theory

Claudio Melis, Giorgio Pia, Elisa Sogne, Andrea Falqui, Stefano Giordano, Francesco Delogu, Luciano Colombo

By combining electron microscopy measurements, atomistic simulations and elastic homogenization theory, we theoretically investigate the Young’s modulus of nanoporous Au structures. Based on atomistic replicas generated starting from experimental tomographic evidence, atomistic simulations reveal…

Photovoltaic-thermoelectric (PV-TE) hybrid system for thermal energy harvesting in low-power sensors

Riham Farhani, Chouaib Ennawaoui, Abdelowahed Hajjaji, Yahya Boughaleb, Atika Rivenq, Yassin El Hillali

Nowadays, population growth and increasing urbanization imply a growing demand for energy, which must be achieved while limiting polluting emissions. To meet this dual challenge, the use of renewable energy resources and energy generators is essential. Thermoelectric generators (TEGs) have…

Chapter 3. Optimizing the Current Type 2 Diabetes Antidiabetics with Nanotechnologies: Where Do We Stand?

Amar Abderrahmani, Sabine Szunerits, Stéphane Dalle, Rabah Boukherroub

Type 2 diabetes (T2D) is the most prominent form of diabetes worldwide. In the history of T2D, insulin resistance of liver, muscle and adipose tissue first develops with no apparent clinical signs. Hyperglycemia ensues when β-cells fail to release a sufficient insulin level into the bloodstream to…
