The Colorado School of Mines was awarded a $548,676 Project Grant from the National Science Foundation's Technology, Innovation, and Partnerships program to develop new alloy materials and device designs extending wireless communications to the next stage of 5G operation. Through the award, the School will screen and develop novel piezoelectric alloys with higher acoustic velocities than existing options using high-throughput experimentation guided by first-principles computational tools. This work will increase understanding of complex multi-cation and multi-anion alloy fabrication and electromechanical properties. The School will couple development and optimization of the higher velocity, lower permittivity alloys to novel device structures demonstrating acoustic resonators operating above 6 GHz. Co-design of materials exhibiting enabling properties and resonators leveraging those properties is expected to yield compact, low-cost, high-efficiency filters for >6 GHz wireless devices. The three-year award beginning May 15, 2023 supports the School's effort to address scientific questions around accurately computing alloy sound speeds and extend wireless components into emerging 5G communication bands through a materials-device co-design approach.
