Project Description:Tabrizian group, at the University of Florida, has been at the forefront of developing a unique solution based on the use of linear and non-linear electronic-phononic interactions in nano- mechanical systems. Tabrizian’s group is exploring novel nano-acoustic technologies that fuse the non- reciprocal acoustoelectric wave propagation physics in single-crystal germanium (Ge) with frequency- selective piezoelectric and ferroelectric transducers to realize monolithic spectral processors for full- duplex RFFE. Ultra-low-loss Ge nano-acoustic resonators, filters, isolators and circulators, enhanced with atomically engineered transducers, are developed in Tabrizian lab with performances substantially surpassing state-of-the-art electronic, electromagnetic, photonic, and ferrite-based counterparts. The novel non-reciprocal Ge nano-acoustic technology will transform wireless mobile systems through enabling full-duplex systems and radical increase in data rates to address the urgent need for communication capacity enhancement in the IoT era.
