Multifunctional Hybrid Metamaterial Designs Towards Advanced Device Applications

Integrating two functional materials through a nanoengineering approach in a hybrid material thin film form provides unlimited possibilities in developing new materials with multifunctionalities and/or unique functionalities for future plasmonics and optics, electronics and energy applications. In this talk, we review our recent success in demonstrating various new classes of complex hybrid metamaterials in oxide-metal, oxide-nitride, nitride-metal and multiple three phase systems. We have integrated these new hybrid metamaterials in plasmonics and photonics, high density magnetic data storage systems, magnetic tunnel junction devices, and resistive switching devices for neuromorphic computing. Owing to the high density vertical aligned interfaces, the hybrid material systems demonstrated enhanced vertical anisotropy in optical, magnetic and ionic transport properties and strong coupling properties. Enabled by the versatile materials selections and structural tunability, these new nanoscale hybrid metamaterials could enable future complex electro-magneto-optical coupled devices, multifunctional sensors, metal-free hybrid plasmonic metamaterials, and energy applications.
