Topological-Insulator-Based Gap-Surface Plasmon Metasurfaces

Topological-Insulator-Based Gap-Surface Plasmon Metasurfaces

Topological insulators (TIs) have unique highly conducting symmetry-protected surface states while the bulk is insulating, making them attractive for various applications in condensed matter physics. Recently, topological insulator materials have been tentatively applied for both near- and far-field...
