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…

Tunability of Bragg band gaps in one-dimensional piezoelectric phononic crystals using external capacitances

Sebastien Degraeve, Christian Granger, Bertrand Dubus, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

A one-dimensional stack of identical piezoelectric rods is investigated. The device exhibits a band gap related to electrical boundary condition. A separate control of the central frequency and of the width of the band gap is performed by an electrical boundary condition involving two different…

Modeling and de-embedding the interferometric scanning microwave microscopy by means of dopant profile calibration

L. Michalas, Fei Wang, Charlene Brillard, Nicolas Chevalier, Jean-Michel Hartmann, Romolo Marcelli, Didier Theron

This paper presents the full modeling and a methodology for de-embedding the interferometric scanning microwave microscopy measurements by means of dopant profile calibration. A Si calibration sample with different boron-doping level areas is used to that end. The analysis of the experimentally…

Near-Field and Far-Field Sensitivities of LSPR Sensors

I. Kaminsky, Thomas Maurer, Rana Nicolas, Mickaël Renault, Thomas Lerond, Rafael Salas-Montiel, Z. Herro, M. Kazan, J. Niedziolka-Jönsson, Jerome Plain, Pierre-Michel Adam, Rabah Boukherroub, Sabine Szunerits

The present study compares the near-field and far-field sensitivities of localized surface plasmon resonance (LSPR) sensors. To put into evidence the difference between far-field and near-field sensors, optical extinction measurements have been performed on gold nanoparticle gratings coated with…

Multiport Reflectometer Based on Subtractive Mixing

Abdelhatif El Fellahi, Kamel Haddadi, David Glay, Tuami Lasri

A compact multiport reflectometer using a new subtractive mixing scheme for the determination of reflection coefficients in the frequency range of 1-10 GHz is proposed. Compared with classical multiport reflectometers, the architecture proposed reduces the design complexity. Comparison between…

Measurement Accuracy and Repeatability in Near-Field Scanning Microwave Microscopy

S. Gu, Kamel Haddadi, A. El Fellahi, Gilles Dambrine, T. Lasri

We report on the accuracy and repeatability tests for near-field scanning microwave microscopy applications by associating a network analyzer and an evanescent microwave probe (EMP). A broadband matching network based on an interferometric technique is used to achieve a strong electromagnetic…

A planar micro thermoelectric generator with high thermal resistance

Zheng Yuan, Katir Ziouche, Zahia Bougrioua, Pascale Lejeune, Tuami Lasri, Didier Leclercq

This paper presents the modelling, design, fabrication and characterization of a planar micro thermoelectric generator (μTEG) which is able to convert waste heat into a few microwatts of electrical power. In order to get a better performance under a large variety of heat sources even if their…
