Abstract
Hybrid systems of silver nanodisks strongly coupled to monolayer tungsten-disulfide (WS) 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.
摘要
银纳米盘与单层二硫化钨（WS）强耦合的混合系统由于其深亚波长局域特性而展现出巨大的室温非线性，从而在固态系统中实现了非线性吸收的超快调制。
