AI Technical Summary
Existing topological phononic crystal devices have fixed structures, making it difficult to achieve multifunctionality and electroacoustic integration, and thus unable to meet the needs of intelligentization.
Design a topological logic gate device based on a topological phononic crystal. The topological phononic crystal is prepared by femtosecond laser etching using zinc oxide single crystal material and phononic crystal electrode layer. Triangular prism surface and bottom electrodes are set on its boundary. Combined with wire output port, the coupling of acoustic waves and electrical signals and logic gate function are realized.
This invention achieves multifunctionality of topological phononic crystals, possessing high robustness and anti-interference capabilities. It enables the electrical output of logic OR gates and XOR gates without altering the structure, providing a new approach to electroacoustic integration.
