Abstract

Valley degree of freedom in monolayer transition metal dichalcogenides have been explored as an information carrier. In a different context, metasurfaces consisting of engineered components have enabled the manipulation of light in unprecedented ways. Here, we demonstrate that by placing a MoS2 monolayer onto a metasurface consisting of asymmetric grooves, valley polarized excitons can be spatially separated even at room temperature.
