Dielectric function of colloidal lead chalcogenide quantum dots obtained by a Kramers-Krönig analysis of the absorbance spectrum

Iwan Moreels, Guy Allan, Bram de Geyter, Ludger Wirtz, Christophe Delerue, Zeger Hens

We combined the Maxwell-Garnett effective medium theory with the Kramers-Krönig relations to obtain the complex dielectric function ϵ of colloidal PbS, PbSe, and PbTe quantum dots (Qdots). The method allows extracting both real (ϵR) and imaginary (ϵI) parts of the dielectric function from the…

Surface microscopy with laserless MEMS based AFM probes

Emmanuelle Algre, Bernard Legrand, Marc Faucher, Benjamin Walter, Lionel Buchaillot

We report here on results of AFM microscopy using laserless MEMS based probes. This new concept of atomic force microscope (AFM) probes using bulk-mode silicon resonators was previously presented [1]. They consist on silicon ring resonators with capacitive transducers and integrated sensing nanotip…

Composite left-right handed metamaterials at terahertz frequencies

Shengxiang Wang, Frédéric Garet, Karine Blary, Eric Lheurette, Jean-Louis Coutaz, Didier Lippens

High-transmissivity left/right-handed metamaterials were fabricated in a multilayered dielectric/hole metal array technology and experimentally assessed at sub-millimeter wave lengths. From the frequency dependence of the scattering parameters, we show the possibility to close the gap between the…

Nonlinear Acoustics of Phase Conjugate ultrasound Waves

Vladimir Preobrazhensky, Philippe Pernod

In this presentation, the principles of nonlinear acoustics of phase conjugate ultrasound waves (PCW) and their applications for nonlinear imaging and flow diagnostics are reviewed. The theoretical basis for description of nonlinear propagation of PCW in inhomogeneous and moving media is presented…
