摘　　要：Hybrid systems of silver nanodisks strongly coupled to monolayer tungsten-disulfide(WS_(2))show giant room-temperature nonlinearity due to their deeply sub-wavelength localized nature,resulting in ultrafast modifications of nonlinear absorption in a solid-state system.

关 键 词：NONLINEARITY SILVER DISULFIDE
