Project Description:
Metal-organic frameworks are complex lattice structures composed of metal ion centers joined by organic linker groups. Transition metal dichalcogenides are of great interest for displaying novel quantum properties, especially in heterostructures. Typically, these are made with two layers of a TMD, but the MOF crystal allows for higher degrees of tunability in the architecture than previous TMD-on-TMD stacking schemes, as the structure of the MOF can be modified near endlessly to couple to specific phenomena in the TMD, to give rise to unique superlattice properties. This work explores new methods of synthesizing heterostructures combining the TMD with a 2D MOF that can act as single photon sources. We have developed a method for synthesis of the MOF directly on the TMD to simplify the production process, and investigate the effects of deposition strains on the superlattice.
