Topological insulators are strange stuff – the bulk of this material is insulating and cannot carry an electrical current, yet the surfaces of the same material are conducting. This means that charged ...
Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...
Topological crystals are a revolutionary class of materials that exhibit unique electronic and physical properties due to their non-trivial topological band structures. These materials have garnered ...
