Conference : “International Workshop on Sound-enabled Nanotechnologies » (IWSENT)

The European projects SAWtrain and Phenomen

November 26-29th 2018

Valencia (Spain)

Abstract :

IWSENT is a joint effort by the European-funded projects SAWtrain and PHENOMEN aiming at gathering leading scientists from all over the world working in the emerging field of high frequency vibrations in semiconductor and related materials, with special focus on surface acoustic waves (SAWs), opto-mechanics, high-frequency phonons, and their applications. The dynamic modulation of semiconductor structures by high frequency vibrations provides a powerful tool for the control of the materials properties required for novel functionalities in nanophotonics, nanoelectronics, and quantum information processing. Of special interest are SAWs: these vibrations with GHz frequencies and micrometer-size wavelengths can be generated on a semiconductor chip with standard integrated circuit technology. The combination of SAWs with nanostructures has developed into new interdisciplinary fields ranging from the control of chemical reactions to advanced acousto-optical structures and to GHz quantum acoustics. Moreover, the potential of combined phononics, photonics and radio-frequency (RF) electronic signals allows one to lay the foundations of a new information technology. In particular, the controlled propagation of phonons could lead to low power components, with phonons as information tokens, by themselves or coupled to photons.

IWSENT constitutes an excellent opportunity to start the discussion on phonon-based circuits as well as SAW-based technologies, seeking to explore synergies and to boost the research in the field in the near future.

Thèse : Développement de micro-capteurs de frottement pariétal et de pression pour les mesures en écoulements turbulents et le contrôle de décollement

GHOUILA-HOURI Cécile

Soutenance de thèse
26/10/2018 – 13:30
Amphithéâtre IEMN – LCI, Villeneuve d’Ascq


Résumé :

Le contrôle des écoulements vise à modifier le comportement naturel d’un écoulement fluidique. Dans le domaine des transports, contrôler les phénomènes fluidiques tels que le décollement peut permettre d’économiser du carburant, d’améliorer les performances des véhicules ou encore d’assurer davantage la sécurité des passagers. Dans ce contexte, des capteurs avec de fines résolutions temporelle et spatiale sont requis afin de connaître l’écoulement à contrôler et adapter en temps réel le contrôle.  Dans ce travail, l’objectif a été de développer des micro-capteurs de frottement et de pression pour les mesures en écoulements turbulents et le contrôle de décollement.
Tout d’abord un micro-capteur calorimétrique a été conçu et réalisé par des techniques de microfabrication pour mesurer simultanément le frottement pariétal et la direction de l’écoulement. Le micro-capteur a ensuite été intégré en paroi d’une soufflerie afin de réaliser son étalonnage statique et dynamique et d’étudier sa sensibilité à la direction de l’écoulement. Troisièmement, le micro-capteur calorimétrique a été utilisé pour caractériser des écoulements décollés.  Plusieurs micro-capteurs avec électronique miniaturisée ont été intégrés avec succès dans une maquette de volet et des essais de contrôle actif ont été réalisés. Enfin, la quatrième partie concerne le développement d’un micro-capteur de pression et d’un micro-capteur multi-paramètres réunissant les deux technologies.
L’ensemble de ces micro-capteurs a caractérisé avec succès et montre des résultats prometteurs pour caractériser les écoulements turbulents et permettre la mise en place de contrôle d’écoulement en boucle fermée.

Development of wall shear stress and pressure micro-sensors for turbulent flows measurements and flow control

 

Summary :

Flow control aims at artificially changing the natural behaviour of a flow. In transport industries, controlling fluidic phenomena such as boundary layer separation allowssaving fuel and power, improving vehicles performances or insuring passenger’s safety. In this context, sensors with accurate spatial and temporal resolution are required. Such devices enable to estimate the flow to control and allow real-time adaptation of the control. In this work, the objective is to develop wall shear stress and pressure micro-sensors for turbulent flows measurements and flow separation control.
Firstly, a calorimetric micro-sensor was designed and realized using micromachining techniques for measuring simultaneously the wall shear stress amplitude and the flow direction. Secondly, the micro-sensor was flush-mounted at the wall of a wind tunnel for static and dynamic calibrations. Thirdly, it was used to characterize separated flows. Several configurations were studied: separation on airfoil profile, separation and reattachment downstream a 2D square rib and the separation on a flap model. Several micro-sensors with embedded electronics were successfully integrated on a flap model and active flow control experiments were performed. Finally, the fourth part of the document concerns the development of a pressure micro-sensor and the development of a multi-parameter micro-sensor combining both technologies.
All these micro-sensors have been successfully realized and characterized and demonstrate promising results for measuring turbulent flows and implementing closed loop reactive flow control.

Abstract :

To understand and mitigate the impact of noise sources on an aircraft, aeroacoustic researchers are in need of a high performance, low cost microphones to address the increasing noise restrictions on commercial aircraft. Existing commercial sensors, even with their relatively high cost, in some cases constrain the quality and type of measurement that may be achieved. This talk presents the design, fabrication and calibration developments of the first truly flush-mount piezoelectric microelectromechanical (MEMS) dynamic pressure sensor with associated packaging for aircraft fuselage arrays. Through-silicon-vias (TSVs) are incorporated into the fabrication of the sensor to eliminate front-side wire bonds and enable an overall flush surface for the packaged sensor that minimizes flow disturbance. The developed packaging method for the sensor demonstrates an overall flushness to within 10 μm, showing substantial improvement from any previously reported efforts.

Abstract :

For realistic 3-D feedback flow control applications, wall measurements tend to be more practical than velocity field measurements. The measurement of mean and fluctuating wall shear-stress and pressure in a boundary layer finds applications both in industry and the scientific community. Time-resolved data can provide physical insight into complex flow phenomena, including turbulent viscous drag, transition to turbulence, and flow separation. The ability for the direct measurement of wall shear-stress as a vector field offers advantages over indirect measurements for pressure sensing for separation detection and flow state estimation for 3D flow control applications. Specifically, when the control objective is often skin-friction or pressure drag reduction, a direct measurement of these quantities may be preferable. This talk presents the design, fabrication and calibration developments of a direct MEMS-based capacitive shear stress sensing system to address both fundamental physics measurements and flow control applications.

Abstract :

In this talk, a review of recent advancements on simultaneous information and energy transmission (SIET) is presented. More specifically, SIET refers to communication systems in which a set of transmitters aim to simultaneously carry on two tasks: information transmission to a set of information receivers (IRs); and energy transmission to a set of energy harvesters (EHs). The performance of SIET is often measured by the information and energy transmission rates that can be simultaneously achieved under certain reliability constraints, e.g., decoding error probability (DEP) and energy shortage probability (ESP). The fundamental limits of SIET consist of the largest set of information and energy rates  that can be simultaneously achieved with bounded DEP and ESP. In general, these fundamental limits are often referred to as the information-energy capacity region. The talk focuses on the study of the information-energy capacity region of three channel models: point-to-point channels, multiple access channels and interference channels.

Thèse : Structure et propriétés de réseaux cohérents de nanocristaux semi-conducteurs

Athmane TADJINE

Soutenance de thèse

jeudi 27 septembre 2018 à 10h00

amphithéâtre de l’IEMN

 Abstract :

La nanostructuration de matériaux semi-conducteurs permet de modifier le comportement des porteurs de charge. Ces modifications sont causées par les effets de confinement quantique. Dans cette thèse, nous étudions par des approches théoriques (numériques et analytiques) les propriétés de réseaux cohérents de nanocristaux semi-conducteurs. Ces réseaux sont expérimentalement obtenus par des méthodes ascendantes (bottom-up) d’auto-assemblage orienté. Nous montrons que leurs structures de bandes électroniques peuvent être modélisées par un simple Hamiltonien effectif dont les énergies propres sont analytiques.  En outre, nous proposons une méthode descendante (top-down) de nano-fabrication consistant en la gravure de puits quantiques semi-conducteurs par des méthodes de lithographie. Cette approche permet de reproduire artificiellement des réseaux bidimensionnels à fort intérêt et comportant des fermions de Dirac tels que le nid d’abeilles, le kagome et le Lieb. Nous étudions ensuite l’effet d’un champ magnétique statique sur un nanocristal isolé, puis sur un réseau de nanocristaux en nid d’abeilles dans lequel nous prédisons l’apparition de grands moments magnétiques. Enfin, nous montrons que dans les réseaux carrés PbSe,  un désordre original portant sur les signes des termes de couplage entre nanocristaux apparaît. Nous montrons que ce désordre est réductible par des transformations de jauge, et nous quantifions le désordre réel (résiduel) ressenti par les électrons.
