Absorption enhancement in 2D nanocrystal superlattices through near-field dipolar coupling: a novel optical phenomenon at the nanoscale

Absorption enhancement in 2D nanocrystal superlattices through near-field dipolar coupling: a novel optical phenomenon at the nanoscale

We demonstrate giant and broadband enhancement of the nanocrystal absorption cross section in close packed nanocrystal superlattices, which is the first report on a collective optical phenomenon in this type of self-assembled metamaterials to date.
