Ultrafast nonlinear absorption enhancement of monolayer MoS_2 with plasmonic Au nanoantennas

In this work, we experimentally study the nonlinear absorption enhancement of saturable absorption and two-photon absorption on a hybrid structure comprising a monolayer MoS_2 and Au nanoantennas via femtosecond I-scan measurement. Specifically, a 13-fold increment in the linear absorption ...
