A Phonon Scattering Bottleneck for Carrier Cooling in Lead Chalcogenide Nanocrystals

Pieter Geiregat, Christophe Delerue, Yolanda Justo, Michiel Aerts, Frank Spoor, Dries van Thourhout, Laurens Siebbeles, Guy Allan, Arjan J Houtepen, Zeger Hens

The cooling dynamics of hot charge carriers in colloidal lead chalcogenide nanocrystals is studied by hyperspectral transient absorption spectroscopy. We demonstrate a transient accumulation of charge carriers at a high energy critical point in the Brillouin zone. Using a theoretical study of the…

Dispersion curves of 2D rods with complex cross-sections: double orthogonal polynomial approach

J.G. Yu, Jean-Etienne Lefebvre, Ch. Zhang, Faniry Emilson Ratolojanahary

Orthogonal polynomial series approach has been used to analyze the guided wave propagation in structures for about 20 years. These structures have always one infinite dimension in the waveguiding direction and, sometimes a regular finite cross-section (axially infinite solid or hollow cylinder for…

High Frequency Acoustic Reflectometry for Solid/Liquid Interface Characterization: Application to Droplet Evaporation

Julien Carlier, Malika Toubal, Sizhe Li, Pierre Campistron, Dorothée Debavelaere-Callens, V. Thomy, Vincent Senez, Bertrand Nongaillard

Evolution of the local concentration in a 1 mL droplet of ethanol/water mixture during an evaporation process has been followed using high frequency acoustic reflectometry. This method has been developed for wetting characterization on micro/nanostructures and makes it possible to follow…

Sensing of liquid droplets with a scanning near-field microwave microscope

Kamel Haddadi, S. Gu, T. Lasri

We demonstrate a scanning near-field microwave microscope based on an interferometric technique for dielectric characterization in liquid media. The instrumentation combines a vector network analyzer, an interferometry-based matching network and an evanescent microwave coaxial probe. The…

Design of Environmental Biosensor Based on Photonic Crystal Fiber with Bends Using Finite Element Method

Shyqyri Haxha, Ahmed Teyeb, Fathi Abdel Malek, Emmanuel Kofi Akowuah, Iyad Dayoub

In this paper, a biosensor based on photonic crystal fiber (PCF) is proposed and designed using Full-Vectorial Finite Element Method (FVFEM). The proposed PCF sensor consists of three concentric circles surrounding the core. The key optical sensor characteristics such as sensitivity, the field…

Experimental analysis of Zigbee RF signal performance for railway application: Study on a laboratory reduced scale train

Sara Iben Jellal, O. Cohin, S. Baranowski, Ulrich Biaou, Michael Bocquet, Atika Rivenq

Due to its cost and power performance, Zigbee is widely used and can be applied to railway systems. This paper deals with the performance of a Zigbee (IEEE.802.15.4) RF signal, according to several criteria; this analysis is based on an experimental approach and specially on power measurements in…

Cristal phononique piézomagnétique à une dimension : contrôle de la propagation par inductance variable

Marie-Fraise Ponge, Jérôme Vasseur, Olivier Bou Matar, Anne-Christine Hladky, Bertrand Dubus

Cette étude concerne un cristal phononique à une dimension constitué d'un empilement de couches piézomagnétiques identiques. Chaque couche est entourée par une bobine connectée à une inductance extérieure. Les ondes élastiques longitudinales se propageant dans cette structure sont étudiées…
