Complex Hybrid Metamaterials Designs based on Functional Ceramics and Beyond

Abstract
Functional ceramics are widely used in various electronic, optical and magnetic devices, as well as structural components. Coupling their unique multifunctionalities, ceramics and their nanocomposites with unique nanoscale interfaces and defect designs have allowed a new class of ceramic-based hybrid metamaterial designs. In this talk, multiple ceramic-based hybrid metamaterial systems that couple 2 or more functional materials in a vertically aligned nanocomposite (VAN) thin film form, are introduced. Such hybrid metamaterial designs provide unlimited possibilities in developing new materials with multifunctionalities and/or unique functionalities for future plasmonics and optics, electronics and energy applications. The talk will cover some of the pioneering VAN demonstrations in oxide-oxide systems for low field magnetoresistance materials and multiferroics, recent oxide-metal nanocomposites with superior anisotropic optical and magnetic properties, and very recent nitride-metal and nitride-oxide based VANs coupling ferroelectric, ferromagnetic, plasmonic, hyperbolic optical response, and superconductivity in a single material platform. We also demonstrate that it is possible to transfer these epitaxially grown complex hybrid metamaterials onto various device relevant substrates for on-chip integration and flexible sensors. We envision that achieving highly ordered VAN-based hybrid metamaterials will provide enormous opportunities in new device concepts and nanoscale fabrication paths that could not be easily achieved by single materials or current lithography and patterning methods.

She was on the faculty in the Department of Electrical and Computer Engineering at Texas A&M University from 2006 to 2016. Prior to that, she was on the staff in the group of Superconductor Science and Technology at Los Alamos National Laboratory from 2003 to 2006, first as a postdoc and then as a technical staff member. She also served as a program director for the Electronic and Photonic Materials Program in the Division of Materials Science at NSF from 2013-2015.
Wang specializes in high temperature superconductors coated conductors, heteroepitaxy of complex nanocomposites with multifunctionality, nanostructured functional ceramics for solid oxide fuel cells, plasmonics and photonics, ferroelectric and multiferroics, ductile ceramic designs, and radiation tolerance materials. She pioneered the designs of vertically aligned nanocomposites (VANs) thin films for various microelectronics and photonic applications, and the design and processing of ductile high temperature ceramics via non-equilibrium processing techniques. She holds 15 issued and 5 pending U.S. patents that have been licensed to multiple companies. She has published over 790 journal articles (with 35000 citations and an H-index of 90) and presented over 400 invited and contributed talks at various international conferences. She is passionate in inspirational materials research and education and societal services. She serves as an associate editor for Science Advances (since 2018) and a member of MRS Board of Directors (2023-2026). Her major awards include TAMEST O’Donnell Award in Engineering 2015, ASM Silver Medal for Outstanding Materials Scientist in Mid Career 2011, and PECASE 2008. Wang is a fellow of NAI, MRS, APS, AAAS, ACerS, and ASM International.
