[Invited] Millimeter-wave noise and power characterization using in situ tuner

Thomas Quemerais, Daniel Gloria, Sandrine Oeuvrard, Christophe Gaquière, Francois Danneville, Gilles Dambrine, Marina Deng

The advanced micro-and nano-technologies now allows the design of high frequencies integrated circuit with transistors operating at millimeter-wave (MMW) frequencies and beyond. This evolution led us to develop industrial test tools to characterize and validate the models of these transistors.…

Disorder-perturbed Landau levels in high-electron-mobility epitaxial graphene

Simon Maëro, Abderrezak Torche, Thanyanan Phuphachong, Emiliano Pallecchi, Abdelkarim Ouerghi, Robson Ferreira, Louis-Anne de Vaulchier, Yves Guldner

We show that the Landau levels in epitaxial graphene in the presence of localized defects are significantly modified compared to those of an ideal system. We report on magnetospectroscopy experiments performed on high-quality samples. Besides typical interband magneto-optical transitions, we…

Cyclones and attractive streaming generated by acoustical vortices

Antoine Riaud, Michael Baudoin, Jean-Louis Thomas, Olivier Bou Matar

Acoustical and optical vortices have attracted great interest due to their ability to capture and manipulate particles with the use of radiation pressure. Here we show that acoustical vortices can also induce axial vortical flow reminiscent of cyclones, whose topology can be controlled by adjusting…

High frequency acoustic for nanostructures wetting characterization

Sizhe Li, Sébastien Lamant, Julien Carlier, Malika Toubal, Pierre Campistron, Xiumei Xu, Guy Vereecke, Vincent Senez, V. Thomy, Bertrand Nongaillard

Nanostructure wetting is a key problem when developing superhydrophobic surfaces. Conventional methods do not allow us to draw conclusions about the partial or complete wetting of structures on the nanoscale. Moreover, advanced techniques are not always compatible with an in situ, real time,…

Evaluation de la peau du béton à l'aide de la technique des ondes ultrasonores de surface

Bogdan Piwakowski, Jean-Paul Balayssac, Géraldine Villain, Vincent Garnier, Mariusz Kaczmarek, Radoslaw Drelich

Concrete cover degradation is induced by aggressive agents in ambiance, chemicals, moisture, or temperature variations. Due to these degradations, a thin inhomogeneous surface layer usually appears. Its porosity and its elastic modulus are different from the properties of deeper sound concrete.…
