Engineering of dispersion curves and band gaps in a phononic crystal made of pillars on a membrane or substrate

Bahram Djafari-Rouhani, Abdelali Mrabti, Mourad Oudich, Abdellatif Akjouj, Yan Pennec, Bernard Bonello

We present the recent progress in our theoretical work about the acoustic properties of phononic crystals constituted by a periodic array of pillars on a membrane or on a substrate. In the case of a thin membrane, we have shown, in addition to the Bragg gaps, the possibility of a much lower...

5.4 MHz dog-bone oscillating AFM probe with thermal actuation and piezoresistive detection

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

We report on a new concept of Atomic Force Microscope (AFM) oscillating probes using dog-bone resonator with thermal excitation and piezoresistive detection. The resonance frequency is 5.4 MHz and the quality factor is measured about 4,000 in air. AFM images are obtained over PMMA resist sample and...

Impact of BEOL stress on BiCMOS9MW HBTs

Elodie Canderle, P. Chevalier, G. Avenier, N. Derrier, D. Céli, Christophe Gaquière

Stress investigations have been carried out on SiGe HBTs from STMicroelectronics BiCMOS9MW technology. The strain created by the stack of metal connections impacts the base bandgap of the transistors: from the reference to the denser dummies structure, a 9.1 meV bandgap energy variation is pointed...

Performance evaluation of ultra-low frequency underwater acoustic projectors

Bertrand Dubus, Pascal Mosbah, Jean-Rémi Hartmann, Jacky Garcin

Ultra Low Frequency (ULF) underwater waves can travel great distance and are generally used in sonar or oceanography. To generate these waves, underwater transducers, utilized in the 10-400 Hz frequency range, have radiating surfaces whose dimensions are small with respect to the acoustic...
