Effect of mechanical loading on the tuning of acoustic resonances in Ba (x) Sr1-x TiO3 thin films
Nava Setter, Alexander Tagantsev
The effect of mechanical loading on the tuning performance of a tunable Thin Film Bulk Acoustic Wave Resonator (TFBAR) based on a Ba0.3Sr0.7TiO3 (BST) thin film has been investigated experimentally and theoretically. A membrane-type TFBAR was fabricated by ...
Springer US2010Tunable thin film bulk acoustic wave resonator based on BaxSr1-xTiO3 thin film
Nava Setter, Paul Muralt, Alexander Tagantsev
A tunable membrane-type thin film bulk acoustic wave resonator (TFBAR) based on a Ba0.3Sr0.7TiO3(BST) thin film has been fabricated. The resonance and antiresonance frequencies of the device can be altered by applying a dc bias: both shift down with increa ...
2010An ultrasensitive vibrating channel mass sensor based on tunnelling current detection
We present a new design of a mass sensor capable of detecting mass values in the zeptogram range. The sensor comprises a resonant beam and two gate electrodes used to oscillate the beam at its resonance frequency. The detection method is based on the tunne ...
World Scientific And Engineering Acad And Soc, Ag Loannou Theologou 17-23, 15773 Zographou, Athens, Greece2010Electrical tuning of dc bias induced acoustic resonances in paraelectric thin films
Nava Setter, Alexander Tagantsev
A theoretical model for the dc bias dependence of induced acoustic resonances in paraelectric materials is presented. The field dependent piezoelectric constitutive equations were derived from the Landau free energy expansion with respect to the ferroelect ...
2008Polymeric MOEMS variable optical attenuator
Luis Guillermo Villanueva Torrijo, Victor Javier Cadarso Busto
In this letter, we take advantage of the high coefficient of thermal expansion (CTE) of a chemically amplified, epoxy-based negative polymer (SU-8) to define a low-power consumption polymeric variable optical attenuator that combines the working principles ...
2006Magnetic direct generation of acoustic resonances in silicon membranes
High-Q silicon membranes have been fabricated as resonator elements for excitation by magnetic direct generation of acoustic waves. Operating in the thickness shear mode, these inexpensive sensor elements are remotely excited by a planar spiral coil, drive ...
