80 GHz field-effect transistors produced using high purity semiconducting single-walled carbon nanotubes

L. Nougaret, H. Happy, Gilles Dambrine, Vincent Derycke, J.P. Bourgoin, A.A. Green, M.C. Hersam

This paper presents the high frequency performance of single-walled carbon nanotube (SWNT) field-effect transistors, with channel consisting of dense networks of high purity semiconducting SWNTs. Using SWNT samples containing 99% pure semiconducting SWNTs, we achieved operating frequencies above 80…

Phonon surface mapping of graphite : disentangling quasi-degenerate phonon dispersions

A. Gruneis, J. Serrano, A. Bosak, M. Lazzeri, S.L. Molodtsov, L. Wirtz, Claudio Attaccalite, M. Krisch, A. Rubio, Francesco Mauri, T. Pichler

The two-dimensional mapping of the phonon dispersions around the K point of graphite by inelastic x-ray scattering is provided. The present work resolves the longstanding issue related to the correct assignment of transverse and longitudinal phonon branches at K. We observe an almost degeneracy of…

A millimeter-wave microstrip antenna array on ultra-flexible micromachined polydimethylsiloxane (PDMS) polymer

S. Hage-Ali, Nicolas Tiercelin, P. Coquet, R. Sauleau, H. Fujita, Vladimir Preobrazhensky, Philippe Pernod

The use of Polydimethylsiloxane (PDMS), an ultra flexible polymer, as a substrate for the realization of reconfigurable microwave devices in the 60-GHz band is presented. As bulk PDMS is demonstrated to be lossy at millimeter waves, membrane-supported devices are considered. A new reliable and…

New applications of magneto-acoustic phase conjugation

Vladimir Preobrazhensky, Yuri Pyl'Nov, Philippe Pernod, Nikolay Smagin, Alain Merlen

The results of theoretical and experimental studies of application of parametric wave phase conjugation (WPC) for ultrasonic velocimetry of flows are reported. 3D-simulation of propagation of phase conjugate waves (PCW) in nonlinear and moving media is developed. Break of time reversal invariance…

Experimental study on sound and damaged mortar: Variation of ultrasonic parameters with porosity

Zoubeir Lafhaj, Marc Goueygou

The relationship between porosity and ultrasonic parameters of mortar was studied. In order to enhance the sensitivity of the ultrasonic wave to microstructural changes, a high frequency range, 0.6–1.2 MHz, was chosen. The material investigated consists of four mortar mixtures with water/cement…
