High-energy electrons and holes generated upon photoexcitation of plasmonic nanostructures are particularly attractive, as their excess energy can be potentially exploited for driving energetically demanding processes. The study of the ultrafast dynamics of these hot carriers is particularly relevant, as their successful harvesting is strongly...

We study the optical properties of an anisotropic ripple-shaped two-dimensional molybdenum disulfide (MoS2) nanosheet deposited by chemical vapor deposition onto a nanopatterned silica (SiO2) substrate. We unveil a giant anisotropic optical response in the linear and nonlinear regime by a combination of optical extinction measurements,...
