Piezoelectric MEMS resonators based on ultrathin epitaxial GaN heterostructures on Si

P Leclaire, E Frayssinet, C Morelle, Y Cordier, Didier Theron, Marc Faucher

We present the first results about microelectromechanical (MEMS) resonators fabricated on epitaxial nitride semiconductors with thin buffers engineered for MEMS and NEMS applications. These results assess the use of thin buffers for GaN MEMS fabrication. On a 700 nm thick AlGaN/GaN epilayer, a high…

Increased resistance to detachment of adherent microspheres and Bacillus spores subjected to a drying step

Christine Faille, Ilyesse Bihi, Annette Ronse, Gilles Ronse, Michael Baudoin, Farzam Zoueshtiagh

In various environments, including that of food processing, adherent bacteria are often subjected to drying conditions. These conditions have been shown to result in changes in the ability of biofilms to cross-contaminate food in contact with them. In this study, we investigated the consequences of…

Dynamics of liquid plugs in prewetted capillary tubes: from acceleration and rupture to deceleration and airway obstruction

J.C. Magniez, Michael Baudoin, C. Liu, Farzam Zoueshtiagh

The dynamics of individual liquid plugs pushed at a constant pressure head inside prewetted cylindrical capillary tubes is investigated experimentally and theoretically. It is shown that, depending on the thickness of the prewetting film and the magnitude of the pressure head, the plugs can either…

Passive guided wave tomography for corrosion detection

Tom Druet, Bastien Chapuis, Emmanuel Moulin

Structural health monitoring (SHM) consists in embedding sensors in a structure in order to monitor its health status throughout its lifetime. The implementation of SHM systems is restricted in many situations by the necessity to store or to harvest the electric energy necessary to emit the waves…

Structural and optical properties of RF-biased PECVD TiO2 thin films deposited in an O2/TTIP helicon reactor

D. Li, A. Goullet, Michèle Carette, A. Granier, Y. Zhang, Jean-Pierre Landesman

TiO2 thin films are deposited from oxygen/titanium tetraisopropoxide inductively coupled radiofrequency plasmas at low temperature and pressure by a RF-biased PECVD technique. In such a process, the substrate biasing effect (Vb) on the related film composition, structure, morphology, and optical…

Tunable waveguide and cavity in a phononic crystal plate by controlling whispering-gallery modes in hollow pillars

Yabin Jin, Nicolas Fernez, Yan Pennec, Bernard Bonello, Rayisa P Moiseyenko, Stéphanie Hémon, Yongdong P Pan, Bahram Djafari-Rouhani

We investigate the properties of a phononic crystal plate with hollow pillars and introduce the existence of whispering-gallery modes (WGMs). We show that by tuning the inner radius of the hollow pillar, these modes can merge inside both Bragg and low frequency band gaps, deserving phononic crystal…

Improved Cluster-tree Topology Adapted for Indoor environement in Zigbee Sensor Network

Mourad Ouadou, Ouadoudi Zytoune, Driss Aboutajdine, Yassin El Hillali, Atika Rivenq

Wireless Sensor Network (WSN) is a collection of small sensor nodes with aptitude to sense, compute and transmit data that are deployed to observe a physical environment. The sensor node has limited capabilities, especially for energy reserve and memory storage, that is why topology and routing…
