Abstract

In recent years the study of quantum materials, including superconductors, whose properties are dominated by quantum-level phenomena (strong electron coupling, spin-orbit coupling, etc.) has been on the rise. In particular quantum metamaterials, i.e. quantum materials with properties altered by controlling their mesoscale structure in addition to their atomic-level lattices, promise new property profiles. Block-copolymer (BCP) self-assembly in the bulk gives access to numerous mesostructures, including 3D co-continuous cubic networks, that could give rise to novel behaviors in superconductors. However, progress in the field has been limited due to the lack of accessible synthesis routes for high quality metallic materials with such BCP self-assembly directed structures.Researchers at Cornell University have demonstrated a robust, versatile route for production of such mesostructured bulk metals. This has been achieved using high-pressure melt infiltration of liquid metal (e.g. indium) into BCP self-assembly derived mesoporous ceramic templates, e.g. with cubic double gyroid network morphology. The resulting gyroidal indium is a quantum metamaterial with altered superconducting properties relative to bulk indium through modification of fundamental, quantum level characteristics via mesostructured control. Furthermore, the backfilling of double gyroidal ceramic templates with other metals such as aluminum, silver, or gold is predicted to yield materials with novel photonic metamaterial properties.
