Summary: Control over disorder arising from nonequilibrium of atomic positions and distributions of mass offers a promising route to design nanomaterial properties for integration into a wide range of existing and future applications. I will discuss our recently developed method to create highly-spatially localized and well-separated emission sites in a continuous film of nominally bilayer WSe₂ using an ultra-sharp dielectric tip array where we have measured a second order photon correlation parameter to be below 0.3. I will also discuss our very recent discovery of the isotope effect in bilayer ¹⁸⁶W⁸⁰Se₂, which is the first report of isotope engineering in a transition metal dichalcogenide (TMD) two-dimensional material. These discoveries have general implications to defect engineering, and hence impact varied and promising technological areas from energy conversion to quantum communication.
