ABSTRACT: The emergence of two-dimensional (2D) materials and their assembly into artificial heterostructures have triggered new research in every aspect of materials science. In particular, transition metal dichalcogenides (TMDs) such as molybdenum disulfide have found their way into next-generation channel materials for electronic and optoelectronic devices. In these systems the dielectric environment is not only a passive gate insulator, but it actively influences carrier mobility, excitonic properties, and can introduce entirely new device functionalities. This thesis systematically explores three classes of advanced dielectrics integrated with monolayer TMDs, demonstrating that material choice alone can unlock a broad spectrum of applications on a single heterostructure platform.
