Perfect Extinction of Terahertz Waves in Monolayer Graphene over 2-nm-Wide Me…

High carrier mobility and tunability in graphene enable fundamental studies for plasmonics and various applications. Despite its versatility, however,single-layer graphene (SLG) suffers from poor coupling effi ciency to electromagnetic waves, presenting a major challenge for photonic applications.Compared with visible or infrared radiation, terahertz (THz) waves exhibit higher absorption in SL…
