Breaking Piezoelectric Limits with Silicon-Based Surface Acoustic Waves
Researchers at the Indian Institute of Technology (IIT) Bombay and the Raja Ramanna Center for Advanced Technology have demonstrated that silicon can generate high-frequency surface acoustic waves (SAWs) using metallic transducers, bypassing the need for traditional piezoelectric materials. This breakthrough, published in Nano Letters, allows for the integration of acoustic signal processing directly into standard … Read more
