Single optical antenna fabricated on a monolayer MoS2 enhances PL emission up to 4x times.
Two-dimensional materials have been receiving wide attention for applications in semiconductor optoelectronics, however monolayer thickness limits the light-matter interactions resulting in poor light emission and absorption. Aydin group recently demonstrated enhanced light emission from plasmonic nanodisk arrays due to localized surface plasmon resonances. In a collaborative effort between Aydin and Lauhon groups, single dipole and bowtie gold nanoantennas with sub-20nm gaps have been shown to increase photoluminescence emission from a monolayer MoS2.
