Abstract

Abstract : In article number 2003005, Sejeong Kim, Ki Tae Nam, and co‐workers achieve a large degree of circular polarization (≈45%) at room temperature using a single chiral plasmonic nanoparticle on a transition metal dichalcogenide (TMD) monolayer. The chiral nanoparticle also induces circularly‐polarized luminescence with a linear excitation, which has been rarely reported.
