Colossal Modulation of Mechanical Resonance with temperature in single‐Crystalline SrTiO3 Microbridges Integrated on Silicon

Advanced Electronic Materials, EarlyView.
The structural characteristics and resonant mechanical behavior of suspended microbridges comprised of single‐crystalline SrTiO3 that has been grown on silicon are presented. Due to differences in thermal expansion between the SrTiO3 and silicon, we find that the resonant frequencies of the microbridges are not only enhanced, but also hyper‐sensitive ...

A Multimodal Piezoelectric Vertical Sidewall Architecture for Scalable In‐Plane NEMS Resonators

Advanced Electronic Materials, EarlyView.
A vertical in‐plane piezoelectric resonator design shifts frequency tuning from film thickness to lithographic lateral definition, facilitating monolithic multiband integration. Initially validated via microscale length‐extensional resonators, this cavities‐first fabrication approach scales to the nanoscale for high‐frequency operation.
