讲座摘要
Micro/nano mechanical resonators have found widespread applications in sensing, communication, and quantum systems. This talk highlights our development of nanomechanical resonators towards terahertz (THz) frequencies. At these high frequencies, we expect new applications to arise in next-generation communication technologies and quantum studies at elevated temperatures. Utilizing thin-film lithium niobate (TFLN), we demonstrate electromechanics up to 220 GHz, with the potential to exceed 300 GHz. Additionally, we present a TFLN-based optomechanical platform for sub-THz studies, enabling advancements in quantum phononics and transduction. We also explore strategies to enhance mechanical quality factors through non-contact configurations and superconducting electrodes, promising a transformative impact in both classical communication technologies and fundamental quantum studies.
主讲人简介
Dr. Jiacheng Xie is a Postdoctoral Associate in the department of Electrical Engineering at Yale University, where he also completed his Ph.D. under the guidance of Professor Hong Tang. His research focuses on the development of high-frequency nanomechanical resonators in the sub-THz and THz regimes, with applications in next-generation communication systems and quantum technologies. Notably, has developed the world’s first electromechanical resonator and piezo-optomechanical resonator operating beyond 100 GHz.
