In this report, we describe our progress in new synthesis, fabrication and characterization techniques for building quantum superlatticies using2D materials as the building blocks. Specifically, we develop methods that allow i large-scale growth of aligned-crystal graphene and high quality TMDs monolayers such as MoS2 and WS2 ii wafer-scale atomic layer assembly method for building atomically-precise superlattice and heterostructures, iii lateral and clean patterning of 2D materials for atomically-thin circuitry and iv novel physical properties in both 2D-onlyand 2Dorganic hybrid systems. The development here realizes a set of powerful tools that would enable novel quantum structures with high precision and flexibility beyond conventional methods. Moreover, it provides the solutions for current major barrier for 2D materials e.g., limited scalability while preserving their unique properties, which provide the key foundation for leading these new materials into interdisciplinary and industrial applications. This work is funded by the AFOSR grant FA2386-13-1-4118 Layer-by-Layer Growth of 2D Quantum Superlattices.
