The high overtone bulk acoustic wave resonators made of Y-, Lu Alr01o were studies. The Q c .5—X X 2 I £. factor 1.5 2.0*10 at 3.5 4.0 GHz was experimentally found. 1 INTRODUCTION The practical interest to the investigation o...

High-Overtone Bulk Acoustic Resonator

Film bulk acoustic-wave resonator based ultraviolet sensor

This letter described ultraviolet UV radiation sensing with ZnO based film bulk acoustic-wave resonator FBAR . The resonant frequency upshifted when there was UV illumination on the FBAR. For 365 nm UV light, the frequency upshift was 9.8 kHz with an intensity of 600 W /cm2, and the detection limit of the sensor was 6.5 nW. The frequency increase in the FBAR UV sensor was proposed to be due to ...

Porous silicon bulk acoustic wave resonator with integrated transducer

: We report that porous silicon acoustic Bragg reflectors and AlN-based transducers can be successfully combined and processed in a commercial solidly mounted resonator production line. The resulting device takes advantage of the unique acoustic properties of porous silicon in order to form a monolithically integrated bulk acoustic wave resonator.

Coupling Two Distant Double Quantum Dots with a Microwave Resonator.

We fabricated a hybrid device with two distant graphene double quantum dots (DQDs) and a microwave resonator. A nonlinear response is observed in the resonator reflection amplitude when the two DQDs are jointly tuned to the vicinity of the degeneracy points. This observation can be well fitted by the Tavis-Cummings (T-C) model which describes two two-level systems coupling with one photonic fie...
