Towards low-trapping GaN-on-silicon material system for 1200 V applications

Alaleh Tajalli, Idriss Abid, Riad Kabouche, Malek Zegaoui, Matteo Meneghini, Gaudenzio Meneghesso, Enrico Zanoni, A Nishikawa, F Medjdoub

This paper presents an assessment of a GaN-on-silicon buffer structure from the epi-wafer providerALLOS Semiconductors GmbH targeting 1200 V power applications. Epiwafers with 150 mmdiameter were grown by MOCVD on Si (111) substrates. Total GaN thickness is 7.1 µm withseveral interlayers for strain…

Anderson localization induced by gauge-invariant bond-sign disorder in square PbSe nanocrystal lattices

Athmane Tadjine, Christophe Delerue

ABSTRACT We study theoretically the problem of electrons moving on a two-dimensional square lattice characterized by nearest-neighbor hopping terms of constant amplitude but random sign. The original motivation came from the discovery that this “bond-sign” disorder can be present in square lattices…

Device for light-matter interaction enhancement in the full THz range for precise spectroscopy of small volume samples

Romain Peretti, Sergey I. Mitryukovskiy, Flavie Braud, Emilien Peytavit, Emmanuel Dubois, Jean-Francois Lampin

We designed, fabricated, characterized and performed the first experimental uses of a device assembling a waveguide and two antennas. The goal of our device is to confine the broadband pulse of a time-domain spectroscopy setup in the slot of the waveguide with the minimum losses and dispersion and…

Folding a focalized acoustical vortex on a flat holographic transducer: miniaturized selective acoustical tweezers

Michael Baudoin, Jean-Claude Gerbedoen, Olivier Bou Matar, Nikolay Smagin, Antoine Riaud, Jean-Louis Thomas

Acoustical tweezers based on focalized acoustical vortices hold the promise of precise contactless 3D manipulation of millimeter down to sub-micrometer particles, microorganisms and cells with unprecedented combined selectivity and trapping force. Yet, the widespread dissemination of this…

[Invited] Metallic ZnO nanocrystals for Mid IR plasmonics

Bruno Masenelli, M.K.H. Taha, Olivier Boisron, Patrice Mélinon, Christophe Delerue, Karine Masenelli-Varlot, Vincent Sallet

Plasmonics has achieved tremendous improvements over the recent decade in sensing (e.g. SERS). However, plasmonics based on noble metal electron gas allows enhancing electromagnetic fields only in the visible and near-IR range. Unfortunately, many molecules exhibit vibrational modes in the mid-IR.…

Six-Port Technology for 5G Millimeter-Wave Localization Systems

Christophe Loyez, Michael Bocquet, Kamel Haddadi

This work deals with six-port technology applied to a localization system operating in the millimeter-wave frequency band. The proposed system is mainly based on a MMIC 60 GHz six-port circuit which is designed and manufactured with passive mixers, 90° phase-shifters, active and passive dividers to…
