Journal ArticleDOI
Aluminum scandium nitride thin-film bulk acoustic resonators for wide band applications
TL;DR: In this article, a c-textured Al(1−x)ScxN-based bulk acoustic wave resonator (FBAR) was fabricated and characterized as a function of the Sc concentration for the first time.
Journal ArticleDOI
Shear mode AlN thin film electro-acoustic resonant sensor operation in viscous media
TL;DR: In this article, a shear mode thin film bulk acoustic resonator (FBAR) operating in liquid media together with a microfluidic transport system is presented, which has a resonance frequency of around 1.2 GHz and a Q value in water of around 150.
Journal ArticleDOI
Thin film Lamb wave resonators in frequency control and sensing applications: a review
TL;DR: In this article, the authors make an overview of the progress made during the last decade with regard to a novel class of piezoelectric microwave devices employing acoustic Lamb waves in micromachined thin film membranes.
Journal ArticleDOI
Micromachined One-Port Aluminum Nitride Lamb Wave Resonators Utilizing the Lowest-Order Symmetric Mode
TL;DR: In this article, the performance of one-port aluminum nitride (AlN) Lamb wave resonators utilizing the lowest-order symmetric mode with electrically open, grounded, and floating bottom electrode configurations are theoretically and experimentally investigated.
Journal ArticleDOI
Temperature compensation of liquid FBAR sensors
TL;DR: In this article, an almost complete temperature compensation of the second harmonic shear mode was observed for an oxide thickness of 1.22 µm for an FBAR consisting of 2 µm thick AlN and 200 nm thick Al electrodes.
