Sensing light and sound velocities of fluids in 2D phoxonic crystal slab

Yan Pennec, R. Moiseyenko, Bahram Djafari-Rouhani, S. Amoudache, R. Tigrine, R. Lucklum, A. Khater

We study theoretically the potentiality of dual phononic-photonic (the so-called phoxonic) crystals for sensing applications. In this work, we study the transmission normal to a periodically perforated silicon slab when the surrounding medium is a liquid. We investigate the existence of well-...

Impact du recuit d'activation sur la passivation par Al2O3 du silicium type p Cz

Matthieu Pawlik, Jean-Pierre Vilcot, Mathieu Halbwax, M. Gauthier, N. Le Quang

L'Al2O3 déposé par ALD est un diélectrique bien connu pour la passivation de surface du silicium type-p. Cependant, une étape de recuit post-dépôt est nécessaire pour activer la passivation. Grâce à des mesures de densités de charges effectives, de défauts d'interface, temps de vie de...

Noise performance of frequency modulation Kelvin force microscopy

Heinrich Diesinger, D. Deresmes, Thierry Melin

Noise performance of a phase-locked loop (PLL) based frequency modulation Kelvin force microscope (FM-KFM) is assessed. Noise propagation is modeled step by step throughout the setup using both exact closed loop noise gains and an approximation known as "noise gain" from operational...

High reference impedance reflectometer for nonresonant matching of near-field microwave microscope tip probe

D. Glay, A. El Fellahi, T. Lasri

In this letter, we present a nonresonant high impedance reflectometer integrating a tip probe dedicated to near-field microwave microscopy. A 1-kohms reflectometer is fabricated by using lumped elements to validate the approach proposed to solve the problem of impedance mismatch between the probe...

A Novel Dog-Bone Oscillating AFM Probe with Thermal Actuation and Piezoresistive Detection

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

In order to effectively increase the resonance frequency and the quality factor of atomic force microscope (AFM) probes, a novel oscillating probe based on a dog-bone shaped MEMS resonator was conceived, designed, fabricated and evaluated. The novel probe with 400 μm in length, 100 μm in width and...
