Fabrication and Characterization of Two-Dimensional Material Heterostructures for Electronic Applications

Two-dimensional (2D) materials have attracted significant attention in recent years due to their unique physical and electronic properties. Graphene, noted for its exceptional strength, high electrical conductivity, and potential in quantum technologies; molybdenum disulfide (MoS₂), valued for its tunable optoelectronic characteristics; and hexagonal boron nitride (hBN), prized for its chemical stability and dielectric behavior, are among the most studied examples. By stacking these materials in various combinations and orientations, we aim to exploit their complementary properties for advanced electronic and computing applications. Our experiments utilize both standard laboratory equipment and custom-built instruments. We have successfully assembled multiple heterostructures composed of different material combinations and characterized them using the university's scanning electron microscope. Moving forward, we plan to investigate the electronic and optical properties of these stacks for their relevance to next-generation device technologies.
