Thermal management of electronic devices by composite materials integrated in silicon

Emmanuel Ollier, U. Soupremanien, V. Remondiere, J. Dijon, H. Le Poche, A.L. Seiler, F. Lefevre, S. Lips, Christophe Kinkelin, Nathalie Rolland, Paul-Alain Rolland, Malek Zegaoui, S. Lhostis, P. Ancey, B. Descouts, Y. Kaplan

As the power of electronic systems is increasing, thermal fluxes are getting higher, up to more than 100 W/cm2 in the more critical cases. They result in hot spots with various consequences, especially performance reduction and reliability issues. Most of the prior research has been focused on…

Waves in periodic media : Fourier analysis shortcuts and physical insights, case of 2D phononic crystals

Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

Phononic crystal is a structured media with periodic modulation of its physical properties that influences the propagation of elastic waves and leads to a peculiar behaviour, for instance the phononic band gap effect by which elastic waves cannot propagate in certain frequency ranges. The…

Room-temperature quantum spin Hall effect in HgTe honeycomb superlattices

Cristiane Morais Smith, Wouter Beugeling, Efterpi Kalesaki, Yann-Michel Niquet, Christophe Delerue, Daniel Vanmaekelbergh

The recent experimental realization of self-assembled honeycomb superlattices of truncated semiconducting nanocrystals has opened a new path to engineer graphene-like structures. Atomistic band-structure calculations for honeycomb lattices of PbSe and CdSe have shown a rich band structure, with…

Active control of a piezoelectric phononic crystal using electrical impedance

Sid Ali Mansoura, Pierre Maréchal, Bruno Morvan, Anne-Christine Hladky, Bertrand Dubus

We consider a one dimensional Phononic Crystal (PC) based on a stack of plates including piezoelectric layers. The model takes into account electrical external circuit connected to the piezoelectric layers with the exception of the layer for which the impedance is evaluated. Only longitudinal waves…

Interferometric Near-field Microwave Microscopy Platform for Electromagnetic Micro-analysis

Kamel Haddadi, Jaouad Marzouk, Sijia Gu, S. Arscott, Gilles Dambrine, Tuami Lasri

We report an original 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 dedicated evanescent microstrip probes fabricated in…

Two types of MEMS-based oscillating AFM probes

Zhuang Xiong, Estelle Mairiaux, Benjamin Walter, Marc Faucher, Lionel Buchaillot, Bernard Legrand

Most of the commercial Atomic Force Microscope ( AFM) oscillating probes are based on micro-scale cantilevers enabling measurement with pico-Newton force resolution in vacuum. However, the cantilever probes suffer from a degradation of both resonance frequency and quality factor when operating in…

Magneto-transport subband spectroscopy in InAs nanowires

Florian Vigneau, Vladimir Prudkovskiy, Ivan Duchemin, Walter Escoffier, Philippe Caroff, Yann-Michel Niquet, Renaud Leturcq, Michel Goiran, Bertrand Raquet

We report on magnetotransport measurements in InAs nanowires under a large magnetic field (up to 55 T), providing a spectroscopy of the one-dimensional electronic band structure. Large modulations of the conductance mediated by a control of the Fermi energy reveal the Landau fragmentation, carrying…
